The coupling between solid and fluid phases is enforced according to the effective stress principle taking suction dependency and volume change of the effective stress parameters into account. The hydraulic hysteresis is accounted for through the effective stress parameter and the soil water characteristic curve. The spatial discretization of the governing equations is achieved using finite element method, whereas the time integration is conducted using the Newmark scheme. The numerical results are then presented, and the effect of hydraulic hysteresis on dynamic response of unsaturated soils is particularly emphasized."> <meta name="citation_reference" content="citation_author=OC Zienkiewicz;citation_author=YM Xie;citation_author=BA Schrefler;citation_author=A Ledesma;citation_author=N.

The coupling between solid and fluid phases is enforced according to the effective stress principle taking suction dependency and volume change of the effective stress parameters into account. The hydraulic hysteresis is accounted for through the effective stress parameter and the soil water characteristic curve. The spatial discretization of the governing equations is achieved using finite element method, whereas the time integration is conducted using the Newmark scheme. The numerical results are then presented, and the effect of hydraulic hysteresis on dynamic response of unsaturated soils is particularly emphasized.</p> </div> <p><i>© The Authors, published by EDP Sciences, 2016</i></p> <div class="license"> <p><a rel="license" href="http://creativecommons.org/licenses/by/4.0/"><img alt="Licence Creative Commons" src="https://i.creativecommons.org/l/by/4.0/88x31.png"></a>This is an Open Access article distributed under the terms of the <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">Creative Commons Attribution License 4.0</a>, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.</p> </div> </div> </div> <div id="metrics-tabs" data-doi="10.1051/e3sconf/20160908013" data-edps_ref="e3sconf_eunsat2016_08013"> <nav class="toolbar"> <button class="toolbar-item" id="metrics-siq">Current usage metrics</button> <button class="toolbar-item" id="info">About article metrics</button> <button class="toolbar-item" id="return">Return to article</button> </nav> <div class="panel" data-for="metrics-siq"> </div> <div class="panel" data-for="metrics-alm"></div> <div class="panel" data-for="info"> <p>Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.</p> <p>Data correspond to usage on the plateform after 2015.
