Summary or description

In this paper, a model of laminated plates called M4-5N and validated in a previous paper is modified in order to take into account damage at the interfaces between layers. Displacement discontinuities at the interfaces are considered in the model. These discontinuities are calculated by means of a damage model. This damage model involves non linear equations. In order to compute the model, the LATIN method is employed. With this method, two sub-problems are considered: one is linear and the other is non linear. In the linear problem the non-linear equations of the model are linearized. By iterating the resolution of each sub-problem, one obtains the solution of the global problem. The method is then applied to the resolution of a free edge problem of a composite laminate. Calculations prove that the model can help predict delamination in these laminates.
