What is Non-Linear Analysis with Code_Aster about?

This document provides an overview of solving non-linear problems in mechanics using finite element methods and Code_Aster. It first describes different sources of non-linearity including large displacements, material non-linearity, and contact/friction. It then presents theoretical elements such as continuum equations, finite element discretization, and the Newton-Raphson method. Finally, it outlines the general incremental/iterative algorithm used to solve non-linear problems by parametrizing over pseudo-
