Basic concepts of mechanical engineering

This module provides the basic concepts needed to understand the different mechanical behaviors of materials and see how they can be studied using experiments or models. The module will begin with a basic review of continuum mechanics in 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's modulus, compressibility, shear modulus, Poisson's ratio, etc.) for all types of materials (metals, composites, polymers, etc.). After studying the links between different microstructures and mechanical properties, we will present the main tests used to characterize the mechanical behavior of materials. The basic concepts 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 we will show how their parameters can be identified. The module will end with a presentation of dynamic analysis methods (DMA).
