Abstract
A review of recent work characterizing composite delamination failure in fatigue is presented. Results from tensile fatigue tests on unnotched laminates are highlighted to demonstrate the influence of delamination on stiffness, strength, and life. The use of fracture mechanics to achieve a generic characterization of delamination is demonstrsted. A fatigue design philosophy is proposed based on an understanding of composite delamination behavior.
