A total fatigue life model for mode I delaminated composite laminates

Fracture mechanics based total fatigue life model for delaminated composite structures is presented. The model includes the delamination growth in three domains, namely subcritical, linear, and final fracture. The resistance increases due to matrix cracking and fiber bridging in the case of unidirectional composites; and tow splitting, separation, bridging and breaking in the case of woven/braided fiber composites were included through...
