摘要

The computational modelling of multi-layered multidirectional composite materials presents particular difficulties, and there- fore an experimental tool is required that is able to validate any proposed models at a level of detail appropriate to the complexity of the laminate. Such a tool requires, of course, that it in its turn be duly validated. This paper proposes the measurement of energy release rate for a delamination intersecting the edge as a suitably demanding and relevant criterion and the method of moire interferometry as the experimental tool. The validation of the method is carried out against standard geometries and protocols.
