Nonlinear Analysis of Woven Fabric Composite Materials by Homogenization Method Considering Microscopic Fracture

Textile composites are becoming more and more important in engineering field. Need for computational simulations of their mechanical behaviors is also growing. In this study, a nonlinear homogenization method has been developed for the analysis of fracture behaviors of woven fabric composite materials. First, the mechanical behaviors of flat plates made from woven fabric composite materials were analyzed under various loading conditions, and then the reduction of modulus of elasticity by microscopic fracture was calculated precisely. Next, the nonlinear fracture analysis of a plate with an open hole was carried out. It is revealed that the knee points and notched strength are able to be predicted.
