Such models benefit from a good representation of the local 3D stress field, especially inter-laminar stresses which are natural generalized stress unknowns arising in their derivation. We extend their construction to situations involving onset and propagation of interfacial delamination. We propose a variational formulation relying on a continuous damage description of the opening and sliding interfacial degradation processes using two damage variables. A mixed-mode delamination propagation criterion can be obtained through proper coupling between both variables. Finally, the model predictions are validated against classical delamination tests in pure and mixed modes. %G English %2 https://enpc.hal.science/hal-03639729/document %2 https://enpc.hal.science/hal-03639729/file/layerwise_delamination.pdf %L hal-03639729 %U https://enpc.hal.science/hal-03639729 %~ ENPC %~ CNRS %~ UR-NAVIER %~ PARISTECH %~ IFSTTAR %~ UNIV-EIFFEL %~ U-EIFFEL
