Abstract [en]

In this paper we present a theoretical framework which allows us to determine the whole set of thermo-mechanical constants of the damaged laminates a function of crack density in different layers. In this approach closed form expressions are obtained which contains the ply properties, laminate lay-up and crack density as the input information. It is shown that the crack face opening and crack face sliding displacement normalized with respect to load are important parameters in these expressions affecting the level of properties degradation. They are determined in this paper using generalized plain strain FEM analysis results for non-interactive cracks. The methodology is validated and the possible error introduced by the non-interactive crack approach is estimated comparing with the 3-D FEM solution for cross-ply laminate with two systems of orthogonal cracks in plies. A limited number of experimental data are presented and used for further verification. [Material: GF/EP.]
