This paper presents a finite element model based on the Multiparticle Model of Multilayered Materials (M4) developed in Institut Navier-LAMI during the last years. The laminated plate is considered as a superposition of Reissner plates coupled by interfacial stresses. An eight-node multiparticle element is developed here. This element has 5n degrees of freedom per node (n is the layer’s number of the laminate). A finite element program called MPFEAP has been developed for the implementation of the multiparticle element. The proposed finite element model is capable of computing interlaminar stresses and other localized effect which is impossible with classical 2D finite element model. Some examples of free edge problem are provided to illustrate the accuracy of the present element in predicting interlaminar stresses.
