Resumen o descripción

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 plasticity at the interfaces between layers.

Displacement discontinuities at the interfaces are considered in the model. These

discontinuities are calculated by means of a plasticity model which has non linear

equations. In order to compute the model, the LATIN method is employed. The method is

then applied to the resolution of a free edge problem of a composite laminate. The

calculations and a pertinent delamination criterion are used to predict delamination onset in

a family of carbon-epoxy laminates. A good agreement between the theoretical and

experimental results is shown.
