Morphological parameters impact on the properties of 3D composite materials

Abstract eng:
The forecast of thermal and mechanical behavior for reinforced composites is a key issue for those studying these materials from numerical simulations. The effective thermal and mechanical properties are obtained from the microscale information. The periodic Lippmann—Schwinger equation is solved to obtain effective thermal conductivity tensor and the effective stiffness tensor. For electrical properties a novel approach based on connectivity graph analysisis is used. The representative volume elements (RVEs) are generated with a mixture of spherical, ellipsoidal and cylindrical inclusions, by the Random Sequential Adsorption scheme or the time driven Molecular Dynamics. This paper focuses on generating the RVEs and the study of their effective thermal, electrical and mechanical behavior of 3D representative volume elements (RVEs) of multiphased composite materials constituted by a matrix and inclusions randomly distributed with periodic boundaries. Various geometries of inclusions based on corrugated shapes, excavated and/or by removed pieces of inclusions are also considered.
