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.
