The pozzolan used in this study is mussel shell powder. The purpose of this study was to find out how MSP substitution affects concrete strength. Mussel shell powder (MSP) contains important levels of calcium oxide and silicon oxide (SiO<sub>2</sub>) and used as an alternative to Portland cement (PC) to reduce the amount of PC needed to make concrete will perform. The concrete designed according to the Standard Indonesian Method (SNI) and the slump should be between 75mm and 100mm. As a prototype, he built a concrete cylinder measuring 15 cm x 30 cm. The percentage changes when replacing PC with MSP were 0%, 2%, 4%, 6%, and 8%, respectively, with 0% substitute used as the control mixture. The samples evaluated for compressive and tensile strength after 7 and 28 days, respectively. As a result, in terms of compressive strength, the best replacement level for 28-day-old concrete is 6%, with a strength value of 32.46MPa. This resulted in a 21.98% increase in force compared to control. In contrast, replacing 2% PC with MSP achieved the highest shear strength after 28 days, with a strength value of about 2.584MPa, 10.48% higher than witnessed. The two samples all have slightly different chemical group bonds O-H, CH<sub>2</sub>, and C-H. The absorption range of the chemical bond of alkene is 1638.21cm<sup>-1</sup>, and group functional C=O of shell concrete of 1638.21cm<sup>-1</sup>. The group functional of C=O in the sample, but there is no functional group C in the shell. </div> <div> <a data-readmore="{ block: '#abstractTextBlock605469', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 13 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.921.27">Augmenting Material Characterisation via Numerical Analysis to Improve Robustness in Mechanical Property Evaluation</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: R.K.

However, eliminating the systematic biases is a formidable task. This study presents the efforts taken to address three important systematic biases possible in the case of mechanical property evaluation of materials. For a simple tensile strength characterization, misalignment of the specimen with respect to the axis of loading, turning effect in the load application system and geometrical imperfection are considered in the test specimen. These concepts are illustrated using numerical analysis for SAE 1045 steel material. Sheet specimens as per the ASTM standards are modelled and the stress-strain behaviour of the material is bench marked with experimental results. Subsequently, pre-defined cases of (a) specimen misalignment, (b) twisting and (c) geometric imperfections are introduced to study the variations in stress-strain behaviour. It is observed that an inadvertent twisting force coupled with an axial load increases the Von-Mises stress at the mid-section of the specimen increased by about 33% and reduces its fatigue life by 96%. The study clearly brings out the implications of such inadvertent systematic biases occurring in a typical experimental or usage scenario on the component life. It also shows how the numerical computations can offer a robust methodology to assess the bounds of possible deviations. </div> <div> <a data-readmore="{ block: '#abstractTextBlock607518', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 27 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.921.39">Enhancing Structural Vibration Damping in Marine Machinery: A Comprehensive Numerical Investigation with Modal and Harmonic Analysis</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Gaurav Sharma, Adepu Kumaraswamy, Sangram Rath </div> </div> <div id="abstractTextBlock603965" class="volume-info volume-info-text volume-info-description"> Abstract: This article presents a comprehensive study on the damping of vibrations in a motor-pump assembly using viscoelastic and constrained layer damping treatments. The assembly's structural model, designed using SolidWorks software, is subjected to modal and harmonic analyses in ANSYS. The primary goal is to mitigate vibration amplitudes originating from the motor and pump to enhance the assembly's operational performance. Three damping treatments are investigated: Free Layer Damping (FLD), Sandwich Constrained Layer Damping (CLD), and a novel Multilayer CLD approach. The viscoelastic material is modeled using the Prony series method, and its properties are incorporated into the finite element analysis Results demonstrate that the application of damping treatments significantly reduces vibration amplitudes compared to the untreated structure. Among the treatments, the Multilayer CLD approach exhibits the highest damping efficiency, reducing the maximum amplitude by approximately 52% compared to the base structure. The study showcases the advantages of utilizing viscoelastic and constrained layer damping techniques for enhancing vibration control and operational stability in industrial assemblies. The research findings contribute to the field of structural dynamics and vibration control, offering valuable insights into the design and optimization of mechanical systems subjected to dynamic loads. This study opens avenues for further research and practical applications aimed at improving the performance and reliability of motor-pump assemblies and similar industrial equipment. </div> <div> <a data-readmore="{ block: '#abstractTextBlock603965', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 39 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.921.57">Development of the Extrusion Based Food 3D Printer Machine by Modifying Fused Deposition Modelling (FDM) 3D Printer</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Fini Bestiara, Kushendarsyah Saptaji, Tiara Kusuma Dewi, Farid Triawan, Anwar Ilmar Ramadhan, Azmir Azhari </div> </div> <div id="abstractTextBlock601122" class="volume-info volume-info-text volume-info-description"> Abstract: The additive manufacturing (AM) technique is the method to objectify a design by adding the material layer-by-layer. AM for food 3D printing application is used to modify the process of food production in aspects of shape, color, flavor, texture, and nutrition. However, the price of food 3D printers available in the market is too high compared to the benefits they can provide. Addressing this issue, modifying the traditional fused deposition modelling (FDM) 3D printer can be a cheaper alternative that offers more advantages for food production process. This study provides the modification of the FDM 3D printer, such as the designing, fabricating, and setting the new extrusion mechanism to develop the food 3D printer. The modifications are mainly in the extrusion mechanism where the printing material changes from filament into semi-fluid food material. The proposed food 3D printer then tested by printing two different using semi-fluid food materials, i.e., strawberry, and peanut jam. In addition, two different shapes, three different dimensions, and two travel speeds are being selected for the printing test, i.e., 40 and 60 mm/s. As a result, the FDM 3D printer was modified and converted successfully into a food 3D printer. Based on the printing outcomes, it was showed that the strawberry jam has a better surface finish than peanut jam due to its texture consistency. Moreover, the strawberry material also has a lower percentage of error particularly when printed at slower speed. This research is expected to contribute to the development of affordable food 3D printers in Indonesia. </div> <div> <a data-readmore="{ block: '#abstractTextBlock601122', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 57 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.921.67">Experimental Study of the Liquid Cold Plate Cooling System for Lithium-Ion Battery in Electric Vehicle</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Muhammad Raihan Hilmy, Muhammad Aulia Rahman, Indro Pranoto, Khasani Khasani, Joko Waluyo </div> </div> <div id="abstractTextBlock603404" class="volume-info volume-info-text volume-info-description"> Abstract: The battery remains the primary choice of energy and power storage in electric vehicles. To optimize battery performance, manufacturers have developed various technologies, including the battery thermal management system (BTMS). In this study, an experimental investigation was conducted to determine the cooling performance and characteristics of a liquid cold plate cooling system for 18650 lithium-ion battery. The testing involved an 18650 SONY 2100 mAh lithium-ion battery and a 400 W DC Load Tester. Testing was carried out by discharging the battery module and taking data on battery temperature and working fluid temperature to get the heat transfer coefficient. The discharge current varied at 1.25 C, 1.5 C, 1.75 C, and 2 C, while the flow rate was set at 0.2 LPM, 0.5 LPM, and 0.8 LPM. The results indicate that the cooling rate increases as the flow rate rises. The battery temperature rises quicker near the negative pole than at the further location. Furthermore, the pressure drop on the liquid cold plate increases as the flow rate rises, while the highest heat transfer coefficient to pressure drop ratio is observed at 0.2 LPM. </div> <div> <a data-readmore="{ block: '#abstractTextBlock603404', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 67 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.921.75">Research on the Effect of Thermal Coating Temperature on the Fatigue Performance of Wind Turbine Blade Bolts</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Sheng Jun Wu, Hao Wei, Gang Xiong, Wei Feng, Hao Ban </div> </div> <div id="abstractTextBlock607653" class="volume-info volume-info-text volume-info-description"> Abstract: The bolted connection of wind turbine blades is a bridge for transmitting blade loads. In recent years, with the rapid increase in blade length, the fatigue load at the blade root has also been continuously increasing. The bolt fatigue strength has always been a bottleneck in the interface design between blade and wind turbine hub. However, industry standards still hold conservative values for the S/N curve of bolt fatigue, and there are unclear requirements for thermal coatings, The S/N curves provided by the standards in different periods do not meet the actual processing requirements of bolts. In order to study the effect of thermal coating temperature on the fatigue performance of threads and provide a reasonable basis for the subsequent design of long blade bolt connections. Based on the actual processing technology of bolts, experiments were conducted on the S/N fatigue curves of thermal coated bolts at different temperatures. The experimental results prove that the slope of the inclined part of the low-temperature Dacromet test data and the fatigue strength under 2 million cycles are significantly higher than normal temperature Dacromet coated bolts. Low temperature Dacromet can effectively improve the fatigue strength of bolts. </div> <div> <a data-readmore="{ block: '#abstractTextBlock607653', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 75 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 8 of 8 Paper Titles</p> </div> </div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy &amp; Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/read-and-publish-agreements">Read &amp; Publish Agreements</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> &#169; 2024 Trans Tech Publications Ltd.
