Effect of Porosity on the Mechanical Properties of Materials

Abstract

The mechanics of heterogeneous materials is a discipline of the mechanics of materials which is in full expansion. In general, it is interested in structural materials that have heterogeneities that influence their behavior and that cannot be considered homogeneous.

The goal of this discipline is the determination of mathematical forms respecting the fundamental principles of physics and describing the constitutive law of materials with heterogeneities such as different types of pores. This contribution proposes a micromechanical analysis of the damage by meso cracks by highlighting a new homogenization method applied to the porous media to arrive at an effective Young's modulus which we exploited in a thermal shock application.
