Abstract

This study deals with the modelling of the mechanical behaviour of an anisotropic porous material made up of ellipsoidal pores uniaxially oriented according to the geometric parameters that characterize porosity. To do so we used a homogeneization technique based on the finite element method and the coupling of porosity parameters was taken into account. This approach made possible both the introduction of the quantitative and qualitative aspect of porosity and the transcription of mechanical anisotropy due to geometric anisotropy. We thus determined the homogeneized elasticity moduli which traduce rigidity of the ma
