Abstract

In this paper, a woven structure consisting of fiber bundles is defined as a mesostructure and we evaluate the strength of woven fabric composite materials mesoscopically by the homogenization method and anisotropic damage mechanics. A numerical simulation system for virtual strength test has been developed to predict the initial mesoscopic fracture, the fractured location in both macro-and mesostructure and the fracture mode. The mesoscopic fracture mode is shown schematically, which greatly aids in the understanding of the mesomechanics of woven fabric composite materials. This system is effective for material and structure design and proves the necessity of considering the interaction between macro-and mesostructures. Furthermore, the formulation and a numerical example for mesoscopic fracture propagation considering the fracture mode are shown.
