Interlaminar plasticity in composite laminates: Modelling and computation
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 o...

| Sumario: | 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. |
