Description

This module provides the basic notions to understand the different mechanical behaviors of materials and how they can be studied from experiments or models. The module will start with a basic review of continuum mechanics under the Small Perturbation Hypothesis (SPH). The different classes of mechanical behavior of materials will be studied (Elasticity, Visco-elasticity, Plasticity,...) as well as the different mechanical moduli (Young, compressibility, shear, Poisson's ratio,...), for all types of materials (metallic, composites, polymers,...). After studying the links between the different microstructures and the mechanical properties, the main tests used to characterize the mechanical behavior of materials will be explained. The 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 will end with a presentation of the dynamic analysis methods (DMA)
