Large-scale parallel FEM has been developed to simulate damage nonlinear behaviors of woven fabric composites. Anisotoropic damage constitutive based on damage mechanics was employed to simulate various damage modes such as fiber breaking and Transverse cracking. Aditionally ScaLAPACK was utilized for parallel computing. At first, the analytical limit of bandwidth was inverstigated for 2D woven laminar models and 3D woven laminate models. Next the edge effect on damage propagation was analyzed under a tensile loading condition through the companion between unit model of woven architecture and specimen-size ovemll model. Additionally, the effect of 3D woven structure was analyzed.
