The paper concerns the progressive failure analysis of laminates with the in-plane shear nonlinearity accounted for.The nonlinear shear response of the layer is described by the constitutive relation treating the stresses as a function of strains. Thus it can be easily incorporated into the displacement-based FEM codes. The brittle failure mechanisms of the fibers and the matrix of the layer are recognized with the use of the Hashin criterion. The model is implemented into the non-commercial FEM program for the analysis of multifold shells which is based on the 6-parameter nonlinear shell theory of the Cosserat type.
