..., interlaminar shear, and a laminate test for in situ first-ply failure are the strength tests considered. Fracture mechanics test methods discussed include the double-cantilever-beam test, a 90-deg center-notch tension test, and a free-edge-delamination tension test. composite materials fatigue...
