EN In this chapter a particular attention has been directed on the dynamic behavior of materials and structures subjected to dynamic loading. Based on experimental observations, it is clear that the homogeneous material behavior of metals has several non linearities related for example to the strain rate and temperature sensitivity. Therefore, the material description and more precisely the constitutive relation used during numerical simulations for example must include all macroscopic observations. It has to be noticed that constitutive relations described in this chapter are defined in a macroscopic scale. Considering some examples, it is clear that the constitutive relation that was used is the key point to simulate a global problem allowing to avoid as frequently used some numerical tricks to obtain an agreement between experiments and numerical predictions. Following the concept described in this part, the reader will be available to propose new models to fit precisely their own materials for specific applications.
