Abstract : This report presents a brief summary of results obtained in our research program on damage development in fibrous composite laminates. The following technical subjects are described: (i) Effect of fiber breaks on stiffness changes in unidirectional composites. (ii) Stress analysis of transverse cracks. (iii) Progressive transverse cracking of 0/90 laminates. (iv) Analysis of cracks approaching a boundary between two materials. (v) Fatigue of B/Al laminates. Keywords: Composite materials; Epoxy laminates; Laminates; Crack propagation; Cracking(Fracturing); Aluminum; Boron; Balnium.
