摘要

A 3D constitutive damage model is proposed for predicting the progressive failure of laminated composite materials at mesoscopic length scale. The damage initiation and growth functions are based on the experimental phenomenology. The damage evolution laws are defined ensuring the energy regularization thanks to the crack band model. The crack closure effect under load reversal is also considered. The model is specifically formulated to be implemented in a high-performance computing platform, Alya, that enables the use of very fine meshes, ensuring an accurate prediction of the onset and propagation of damage. The reliability and the performance of the proposed formulation are examined simulating a cross-ply laminate and open hole tests under tensile loading.
