Fundamentals of materials mechanics

This module provides a basic understanding of the various mechanical behaviors of materials and how they can be studied using experiments or models. The module begins with an elementary review of continuum mechanics under the Small Perturbation Hypothesis (SPH). The different classes of mechanical behavior of materials will be studied (elasticity, viscoelasticity, plasticity, etc.), as well as the different mechanical moduli (Young, compressibility, shear, Poisson's ratio, etc.), for all types of materials (metals, composites, polymers, etc.). After studying the links between the various microstructures and mechanical properties, the main tests used to characterize the mechanical behavior of materials will be outlined. Basic notions of anisotropic elasticity will also be presented (anisotropic elasticity tensors, orthotropy, transverse isotropy). The basic rheological models commonly used to model these behaviors will then be presented, and it will be shown how their parameters can be identified. The module concludes with a presentation of dynamic analysis methods (DMA).
