Employing a failure criterion with interaction terms to simulate the progressive failure of carbon-epoxy laminates

A failure criterion with the existence of coupling terms is employed to investigate the progressive failure in anisotropic laminated carbon-epoxy plates. The criterion is employed because it is developed recently. Moreover, the criterion allows interaction between fiber and matrix properties. This p...
