The approach enables one to obtain the continuous cooling curve (CCC) diagrams, widely used in metallurgy but seldom adopted for semicrystalline polymers. This method is here exploited to gain new insights on polymorphic behavior of quenched polypropylene and its copolymers with ethylene. Experimental CCC diagrams, covering a wide range of crystallization temperatures in the domains of monoclinic structure and mesophase, are obtained for the first time. The role of counits in affecting the development of the mesophase upon fast cooling is assessed: the critical cooling rate above which a predominant fraction of mesomorphic form is generated significantly decreases with increasing comonomer concentration. This is due to the remarkable hindrance of ethylene counits on the crystallization kinetics of the R-form, which indirectly favors the development of the less affected mesophase. We expect that this concept can be extended to any kind of defects that disturbs the structuring of the monoclinic phase.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="234b4b5fc5aad5731fc1ffe0a13d16ab" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":68067517,"asset_id":49869415,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/68067517/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="49869415"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="49869415"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 49869415; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=49869415]").text(description); $(".js-view-count[data-work-id=49869415]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 49869415; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='49869415']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "234b4b5fc5aad5731fc1ffe0a13d16ab" } } $('.js-work-strip[data-work-id=49869415]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":49869415,"title":"Continuous Cooling Curves Diagrams of Propene/Ethylene Random Copolymers.

We expect that this concept can be extended to any kind of defects that disturbs the structuring of the monoclinic phase.","owner":{"id":25253637,"first_name":"Giancarlo","middle_initials":null,"last_name":"Alfonso","page_name":"GiancarloAlfonso","domain_name":"independent","created_at":"2015-01-23T19:30:05.665-08:00","display_name":"Giancarlo Alfonso","url":"https://independent.academia.edu/GiancarloAlfonso","email":"alN5MnVUY1ZPdCtWSEl1QSttajAxbW9lL1F2TFQ5OWpDUG9sTU00S0dIM0Y5RkhUSXVvVzlTNkdVd3h2K0s3OS0tSU1ETVYxSGVoZGJvbmdzMHlhRHB5QT09--a7ac0750528e5f14fe7232dadfac9236331d1202"},"attachments":[{"id":68067517,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/68067517/thumbnails/1.jpg","file_name":"11380.pdf","download_url":"https://www.academia.edu/attachments/68067517/download_file","bulk_download_file_name":"Continuous_Cooling_Curves_Diagrams_of_Pr.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/68067517/11380-libre.pdf?1626216137=\u0026response-content-disposition=attachment%3B+filename%3DContinuous_Cooling_Curves_Diagrams_of_Pr.pdf\u0026Expires=1742128087\u0026Signature=Ch4dfoBfng7-kKUpgk6IXs2huLCqsjwYhDaF6XRD1dRF1y-JxZuJ8ugcdNl3ilj70g9VJ-PRSpbDdA05J9bR1QM7RlaNvehKAkfEMdNPrmekmBUsgeu9tVVvBcsOOGTnc3tJ3Cx8XFZTqzixpksiD3bVGQAR3mSMU0PtiilNvLuyQQs18b7a7AkEsTfXCjNnKrp6XPGmnkVgmjrpxNxSy1tWqICLOUoD0FGcaNr0E6CWeiK1Cv--w3bwLTM2pBrilF9UOp69O9usw9O7nl-qCSjXNJ9LE1vrDIA6TyMVn5PjIoSR73oQX1TI6hhfWP73oXQwN9bMGiO3o5MU-gk1Qw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":3855,"name":"Polymorphism","url":"https://www.academia.edu/Documents/in/Polymorphism"},{"id":147636,"name":"Cooling Rate","url":"https://www.academia.edu/Documents/in/Cooling_Rate"},{"id":168695,"name":"Polypropylene","url":"https://www.academia.edu/Documents/in/Polypropylene"},{"id":168760,"name":"Macromolecules","url":"https://www.academia.edu/Documents/in/Macromolecules"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES"},{"id":677739,"name":"Calorimetry","url":"https://www.academia.edu/Documents/in/Calorimetry"},{"id":837160,"name":"Crystallization Kinetics","url":"https://www.academia.edu/Documents/in/Crystallization_Kinetics"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="88495336"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/88495336/Design_and_numerical_implementation_of_a_3_D_non_linear_viscoelastic_constitutive_model_for_brain_tissue_during_impact"><img alt="Research paper thumbnail of Design and numerical implementation of a 3-D non-linear viscoelastic constitutive model for brain tissue during impact" class="work-thumbnail" src="https://attachments.academia-assets.com/92459307/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/88495336/Design_and_numerical_implementation_of_a_3_D_non_linear_viscoelastic_constitutive_model_for_brain_tissue_during_impact">Design and numerical implementation of a 3-D non-linear viscoelastic constitutive model for brain tissue during impact</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/DaveBrands">Dave Brands</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://tue.academia.edu/httpwwwtuenl">Gerrit Peters</a></span></div><div class="wp-workCard_item"><span>Journal of Biomechanics</span><span>, 2004</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Finite Element (FE) head models are often used to understand mechanical response of the head and ...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Finite Element (FE) head models are often used to understand mechanical response of the head and its contents during impact loading in the head.

Oscillatory shear experiments on a regular plate-plate rheometer are combined with a phenomenological thixotropy model to obtain model parameters that can be used to describe the steady shear behavior. We compare rate- and stress-controlled kinetic equations for a structure parameter that determines the deformation history-dependent spectrum and, thus, the dynamic thixotropic behavior of the material. We keep the models as simple as possible and the characterization straightforward to maximize applicability. The model can be implemented in a finite element framework as a tool to simulate realistic rubber processing. This will be the topic of another work, currently under preparation.

This device is relatively cheap and enables to obtain linear viscoelastic (LVE) fluid models for practical use in precision mechanics applications. This is an example of reversed engineering, i.e., turning a machine part into a material characterization device. Results are shown for a high-viscosity fluid. The first part of this paper describes the damper design that is based on a high-viscosity fluid. This design is flexure-based to minimize parasitic nonlinear forces such as hysteresis and stick-slip. In the second part of the paper, LVE fluid characterization by means of the damper setup is presented.

Numerically obtained velocity fields and particle tracking schemes are used to provide displacement and stretching fields. From these the location and identification of periodic points can be derived. The presence or absence of these periodic points allows a judgement on the quality of the mixing process. The technique is general and efficient, and applicable to mixing flows for which no analytical velocity field is available (the case for all three-dimensional flows considered in this paper).

In this paper, we numerically study the effect of thixotropy on 2D planar extrudate swell for constant and fluctuating flow rates, as well as the effect of thixotropy on the swell behavior of a 3D rectangular extrudate for a constant flowrate. To this end, we used the Finite Element Method. The state of the network structure in the material is described using a kinetic equation for a structure parameter. Rate and stress-controlled models for this kinetic equation are compared. The effect of thixotropy on extrudate swell is studied by varying the damage and recovery parameters in these models.

It is demonstrated that OXA3,6 facilitates a viscosity suppression when it resides in the molten state. The viscosity suppression is attributed to the interaction of iPP chains/ subchains with molten OXA3,6 nanoclusters. The exact molecular mechanism has not been identified; nevertheless, a tentative explanation is proposed. The observed viscosity suppression appears similar to that encountered in polymer melts filled with solid nanoparticles, with the difference that the OXA3,6 compound reported in this study facilitates the viscosity suppression in the molten state. Upon cooling, as crystal growth of OXA3,6 progresses, the decrease in viscosity is suppressed. Retrospectively, segmental absorption of iPP chains on the surface of micrometer-sized OXA3,6 crystallites favors the formation of dangling arms, yielding OXA3,6 crystallites decorated with partially absorbed iPP chains.

In contrast to the case of flow, the influence of pressure changes on nucleation has been almost neglected so far. In this work we explore the effect of the pressure history on isotactic polypropylene crystallization by applying a brief step-like increase of pressure to the undercooled melt. Using dilatometry and synchrotron X-ray diffraction, an enhancement of crystallization kinetics proportional to the magnitude of the pressure pulse is revealed.

We expect that this concept can be extended to any kind of defects that disturbs the structuring of the monoclinic phase.","owner":{"id":25253637,"first_name":"Giancarlo","middle_initials":null,"last_name":"Alfonso","page_name":"GiancarloAlfonso","domain_name":"independent","created_at":"2015-01-23T19:30:05.665-08:00","display_name":"Giancarlo Alfonso","url":"https://independent.academia.edu/GiancarloAlfonso","email":"alN5MnVUY1ZPdCtWSEl1QSttajAxbW9lL1F2TFQ5OWpDUG9sTU00S0dIM0Y5RkhUSXVvVzlTNkdVd3h2K0s3OS0tSU1ETVYxSGVoZGJvbmdzMHlhRHB5QT09--a7ac0750528e5f14fe7232dadfac9236331d1202"},"attachments":[{"id":68067517,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/68067517/thumbnails/1.jpg","file_name":"11380.pdf","download_url":"https://www.academia.edu/attachments/68067517/download_file","bulk_download_file_name":"Continuous_Cooling_Curves_Diagrams_of_Pr.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/68067517/11380-libre.pdf?1626216137=\u0026response-content-disposition=attachment%3B+filename%3DContinuous_Cooling_Curves_Diagrams_of_Pr.pdf\u0026Expires=1742128087\u0026Signature=Ch4dfoBfng7-kKUpgk6IXs2huLCqsjwYhDaF6XRD1dRF1y-JxZuJ8ugcdNl3ilj70g9VJ-PRSpbDdA05J9bR1QM7RlaNvehKAkfEMdNPrmekmBUsgeu9tVVvBcsOOGTnc3tJ3Cx8XFZTqzixpksiD3bVGQAR3mSMU0PtiilNvLuyQQs18b7a7AkEsTfXCjNnKrp6XPGmnkVgmjrpxNxSy1tWqICLOUoD0FGcaNr0E6CWeiK1Cv--w3bwLTM2pBrilF9UOp69O9usw9O7nl-qCSjXNJ9LE1vrDIA6TyMVn5PjIoSR73oQX1TI6hhfWP73oXQwN9bMGiO3o5MU-gk1Qw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":3855,"name":"Polymorphism","url":"https://www.academia.edu/Documents/in/Polymorphism"},{"id":147636,"name":"Cooling Rate","url":"https://www.academia.edu/Documents/in/Cooling_Rate"},{"id":168695,"name":"Polypropylene","url":"https://www.academia.edu/Documents/in/Polypropylene"},{"id":168760,"name":"Macromolecules","url":"https://www.academia.edu/Documents/in/Macromolecules"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES"},{"id":677739,"name":"Calorimetry","url":"https://www.academia.edu/Documents/in/Calorimetry"},{"id":837160,"name":"Crystallization Kinetics","url":"https://www.academia.edu/Documents/in/Crystallization_Kinetics"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="88495336"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/88495336/Design_and_numerical_implementation_of_a_3_D_non_linear_viscoelastic_constitutive_model_for_brain_tissue_during_impact"><img alt="Research paper thumbnail of Design and numerical implementation of a 3-D non-linear viscoelastic constitutive model for brain tissue during impact" class="work-thumbnail" src="https://attachments.academia-assets.com/92459307/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/88495336/Design_and_numerical_implementation_of_a_3_D_non_linear_viscoelastic_constitutive_model_for_brain_tissue_during_impact">Design and numerical implementation of a 3-D non-linear viscoelastic constitutive model for brain tissue during impact</a></div><div class="wp-workCard_item wp-workCard--coauthors"><span>by </span><span><a class="" data-click-track="profile-work-strip-authors" href="https://independent.academia.edu/DaveBrands">Dave Brands</a> and <a class="" data-click-track="profile-work-strip-authors" href="https://tue.academia.edu/httpwwwtuenl">Gerrit Peters</a></span></div><div class="wp-workCard_item"><span>Journal of Biomechanics</span><span>, 2004</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Finite Element (FE) head models are often used to understand mechanical response of the head and ...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">Finite Element (FE) head models are often used to understand mechanical response of the head and its contents during impact loading in the head.

Oscillatory shear experiments on a regular plate-plate rheometer are combined with a phenomenological thixotropy model to obtain model parameters that can be used to describe the steady shear behavior. We compare rate- and stress-controlled kinetic equations for a structure parameter that determines the deformation history-dependent spectrum and, thus, the dynamic thixotropic behavior of the material. We keep the models as simple as possible and the characterization straightforward to maximize applicability. The model can be implemented in a finite element framework as a tool to simulate realistic rubber processing. This will be the topic of another work, currently under preparation.

This device is relatively cheap and enables to obtain linear viscoelastic (LVE) fluid models for practical use in precision mechanics applications. This is an example of reversed engineering, i.e., turning a machine part into a material characterization device. Results are shown for a high-viscosity fluid. The first part of this paper describes the damper design that is based on a high-viscosity fluid. This design is flexure-based to minimize parasitic nonlinear forces such as hysteresis and stick-slip. In the second part of the paper, LVE fluid characterization by means of the damper setup is presented.

Numerically obtained velocity fields and particle tracking schemes are used to provide displacement and stretching fields. From these the location and identification of periodic points can be derived. The presence or absence of these periodic points allows a judgement on the quality of the mixing process. The technique is general and efficient, and applicable to mixing flows for which no analytical velocity field is available (the case for all three-dimensional flows considered in this paper).

In this paper, we numerically study the effect of thixotropy on 2D planar extrudate swell for constant and fluctuating flow rates, as well as the effect of thixotropy on the swell behavior of a 3D rectangular extrudate for a constant flowrate. To this end, we used the Finite Element Method. The state of the network structure in the material is described using a kinetic equation for a structure parameter. Rate and stress-controlled models for this kinetic equation are compared. The effect of thixotropy on extrudate swell is studied by varying the damage and recovery parameters in these models.

It is demonstrated that OXA3,6 facilitates a viscosity suppression when it resides in the molten state. The viscosity suppression is attributed to the interaction of iPP chains/ subchains with molten OXA3,6 nanoclusters. The exact molecular mechanism has not been identified; nevertheless, a tentative explanation is proposed. The observed viscosity suppression appears similar to that encountered in polymer melts filled with solid nanoparticles, with the difference that the OXA3,6 compound reported in this study facilitates the viscosity suppression in the molten state. Upon cooling, as crystal growth of OXA3,6 progresses, the decrease in viscosity is suppressed. Retrospectively, segmental absorption of iPP chains on the surface of micrometer-sized OXA3,6 crystallites favors the formation of dangling arms, yielding OXA3,6 crystallites decorated with partially absorbed iPP chains.

In contrast to the case of flow, the influence of pressure changes on nucleation has been almost neglected so far. In this work we explore the effect of the pressure history on isotactic polypropylene crystallization by applying a brief step-like increase of pressure to the undercooled melt. Using dilatometry and synchrotron X-ray diffraction, an enhancement of crystallization kinetics proportional to the magnitude of the pressure pulse is revealed. This acceleration is linked to an increase of the number of active nuclei after the short term pressurization, as confirmed by ex-situ optical microscopy observations. Up to an order of magnitude increase in nucleation density is found, for pressure pulses around 600-700 bar. The pressure-induced nucleating effect is interpreted in the light of classical nucleation theory; although a non-classical "barrier-less" nucleation mechanism is also envisaged.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b1569ecd488a63b51817b64dcf01113c" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":87220026,"asset_id":81036788,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/87220026/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="81036788"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="81036788"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 81036788; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=81036788]").text(description); $(".js-view-count[data-work-id=81036788]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 81036788; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='81036788']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "b1569ecd488a63b51817b64dcf01113c" } } $('.js-work-strip[data-work-id=81036788]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":81036788,"title":"Nucleation Induced by ”Short-Term Pressurization” of an Undercooled Isotactic Polypropylene Melt","translated_title":"","metadata":{"publisher":"Elsevier BV","ai_title_tag":"Pressure-Induced Nucleation in Isotactic Polypropylene","grobid_abstract":"Nucleation of semi-crystalline polymers is very sensitive to perturbations of the melt state.
