National audienceWe propose a model to calculate the interface forces in a multilayered medium. The aim of this work is to study damages like delamination and edge effects. The classical analysis methods of multilayered materials do not give enough information about the interface stresses that causes these damages. The model we propose (multiphasic modelisation of multilayered materials M4) permits one to calculate directly these stresses. We present in this paper the M4 model and we estabilish analytical solutions for two problems. In the first one, we show that we can have a good prediction of displacements for a beam flexure problem. In the second one, we compare the interface stresses obtained by the M4 model with solutions found in the...
