They are porous materials characterized by long, straight, unidirectional cylindrical pores, and are obtained via unidirectional solidification from a melt under hydrogen and argon atmospheres. The anisotropic pore morphology of lotus-type materials results in the anisotropy of their mechanical and physical properties. This study aims at investigating the effect of cross-sectional pore shapes on the effective Young's modulus (EYM) of LTPMs. The representative volume element-based finite element homogenization method was used to compute the effective bulk and shear moduli. Subsequently, the EYM was deduced from the effective bulk and shear moduli. The numerical results of the circular pores were validated by comparing them with experimental results. Because the results indicated that the EYM is extremely sensitive to the variation in the pore shapes, a formula for estimating the EYM of LTPMs by considering the pore shapes was developed and validated.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">M MASMOUDI</style></author><author><style face="normal" font="default" size="100%">W KADDOURI</style></author><author><style face="normal" font="default" size="100%">Bourih, K</style></author><author><style face="normal" font="default" size="100%">A BOURIH</style></author><author><style face="normal" font="default" size="100%">S MADANI</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A Multi-Scale Homogenization Procedure for the Estimation of Young&amp;rsquo;s Modulus of Porous Materials by a Multi-Void Shape Model.</style></title><secondary-title><style face="normal" font="default" size="100%">Journal  of Composite and Advanced Materials</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2022</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://doi.org/10.18280/rcma.320401</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">32</style></volume><pages><style face="normal" font="default" size="100%">165-172</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;span style=&quot;color:rgb(30,30,30);Lato,&amp;quot;HelveticaNeue&amp;quot;,Arial,sans-serif;12px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;orphans:2;text-align:justify;text-indent:0px;text-transform:none;widows:2;word-spacing:0px;-webkit-text-stroke-width:0px;white-space:normal;background-color:rgb(255,255,255);text-decoration-thickness:initial;text-decoration-style:initial;text-decoration-color:initial;display:inline!important;float:none;&quot;&gt;Transversal cross-section pores of lotus-type porous materials are generally considered circular; however, they exhibit various pore geometries, which affect their effective properties. The main objective of this work is to develop a generalized model which allows estimating the effective Young’s modulus of multi-void shape porous microstructures by exploiting a relationship developed to evaluate the effective Young’s modulus of porous materials with single-void shape. A procedure based on free software is then proposed to allow the application of the proposed generalized model on real lotus-type porous material images to estimate the effective Young’s modulus. The free tool allows the processing of real porous materials images to obtain multi-void shape microstructures and their pores parameters data. The validation of the generalized model has been established by confronting the obtained results with experimental data taken from literature; an excellent agreement was observed. Therefore, it can be concluded that the proposed procedure associated with the generalized model can be used efficiently for predicting the effective Young’s modulus of the multi-void porous materials, particularly lotus-type porous materials.&lt;/span&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>32</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">A BOURIH</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">S MADANI</style></author><author><style face="normal" font="default" size="100%">T KANIT</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Etude de la plasticité des matériaux poreux : Effet du phénomène de percolation</style></title><secondary-title><style face="normal" font="default" size="100%">GENIE MECANIQUE</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://eprints.univ-batna2.dz/1518/</style></url></web-urls></urls><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">A BOURIH</style></author><author><style face="normal" font="default" size="100%">W KADDOURI</style></author><author><style face="normal" font="default" size="100%">T OUTTAS</style></author><author><style face="normal" font="default" size="100%">S MADANI</style></author><author><style face="normal" font="default" size="100%">A IMAD</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effective yield surface of porous media with random overlapping identical spherical voids</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Materials Research and Technology</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2017</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%"> https://doi.org/10.1016/j.jmrt.2017.01.002</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">Volume 7</style></volume><pages><style face="normal" font="default" size="100%">Pages 103-117</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	The present paper concerns a computational study of a three-dimensional (3&lt;em&gt;D&lt;/em&gt;) unit cells with identical spherical voids in a von Mises matrix. The objective is to estimate the effective plastic flow surface of 3&lt;em&gt;D&lt;/em&gt; microstructures. The work originality is to deal with identical spherical overlapping voids, covering a wide range of stress triaxiality ratios. The effective plastic flow surface is computed for nine distinct loadings on four distinct microstructures. The result indicates that the classical Gurson–Tvergaard–Needleman (&lt;em&gt;GTN&lt;/em&gt;) model obtained using the Fritzen et al.parameters, matches with our numerical simulations.
