Abstract
The one-dimensional study presented in Part 1 of this paper is extended to the case of a two-dimensional layer laminate composite T300/914 subjected to a static bi-tension and shear. The regularization of this problem is due to the use of evolutionary models with delay effect where the velocity of damage is limited. The size of the localization area in the plane of the layers is related to the characteristic time of the model with delay and the loading rate. The work shows that the use of mesomodeling coupled with models of time delay damage evolution has identified the general localization area and has correctly predicted the time of fracture.
