The objective of this study was to model and simulate progressive failure initiating from a notch tip in a laminated fibrous composite subjected to tensile in-plane loading. The micro/macro-level approach was used for this study. The micro-level analysis used the 3-D unit cell model while macro-level analysis used the finite element analysis technique. A cross-ply laminate with double-edge notches was studied to investigate delamination, fiber splitting, and transverse matrix cracking in the structure. Numerical results were compared to previous experimental work.
