摘要：

The problem of crack progression in a laminate consisting of alternate brittle and ductile layers has been addressed. A finite element analysis has been used to calculate stresses in the vicinity of a crack and the results rationalized on the basis of low and high stress bounds associated, respectively, with small-scale yielding and with a shear lag at the interface. Preliminary experiments conducted on Al2O3/Al laminates have been used to assess the crack extension criterion, upon comparison with the stress analysis. Implications for the strength and toughness of laminates are briefly presented.
