Abstract : The results from several research investigations dealing with fracture and fatigue of AS1/3501-6 graphite/epoxy composite laminates are described. Investigations include static tensile fracture of laminates with a hole, crack growth of splits during tension-tension cyclic loading of unidirectional laminates with a hole, static tensile behavior of laminates with a hole, and damage initiation and propagation during compression-compression cyclic loading of a laminate with a hole. This last investigation, using Moire interferometry to detect subsurface delamination, is described.
