The present paper is aimed at discussing a micromechanical based model for the simulation of matrix microcracking damage in composite laminates. In this model, homogenisation techniques are employed for constructing simple explicit damage laws at the ply level and for identifying the main damage parameters. These laws present some shortcomings which are discussed in the text through comparison with analytical solutions based on shear-lag and variational mechanics models for damaged laminates. It is shown that the damage ply laws are not strictly intrinsic since they can be highly influenced by the laminate stacking sequence and by the exact loading conditions applied to the laminate.

Abstract

The present paper is aimed at discussing a micromechanical based model for the simulation of matrix microcracking damage in composite laminates. In this model, homogenisation techniques are employed for constructing simple explicit damage laws at the ply level and for identifying the main damage parameters. These laws present some shortcomings which are discussed in the text through comparison with analytical solutions based on shear-lag and variational mechanics models for damaged laminates. It is shown that the damage ply laws are not strictly intrinsic since they can be highly influenced by the laminate stacking sequence and by the exact loading conditions applied to the laminate.
