Abstract

This study models and simulates progressive failure initiating from a notch tip of a laminated fibrous composite specimen subjected to tensile in-plane loading. The micro/macro-level approach is used. The micro-level analysis uses the 3-D unit-cell model while macro-level analysis uses 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 specimen. Numerical results are compared to previous experimental work.
