Modèle probabiliste d'homogénéisation des plaques multicouches carton-plâtre-carton: expérimentations et simulations

Abstract : This paper deals with a non parametric probabilistic approach for modelling the multilayer cardboard-plaster-cardboard (CPC) thermomechanical behaviour. We present first, the experimental approach which allows the thermomechanical characterization of the CPC taking implicitly into account the hydrous phase. Secondly we present the developed CPC non-linear mean model of homogenization which simulation results are compared to the experimental ones. Finaly we present the probabilistic non linear model of the multilayer homogenization.
