Sophisticated constitutive equations have recently been proposed to describe the mechanical behavior and damage of polymer matrix composites. Using these equations, the finite element method makes it possible to predict the degradation of composite structures. However using standard finite element procedures, theses equations may lead to numerical problems (instabilities, damage localization, . . .) so that meaningful results are difficult to obtain. One of the solutions consists in writing the constitutive equations in a nonlocal framework. The first part of this thesis is consecrated to the study of such methods in a simplified case (homogeneous isotropic material) and to the coupling of such formulation with arc-length algorithm and para...
