Abstract
Fatigue crack growth of foam core sandwich beams loaded in flexure has been investigated numerically. Extensive fatigue data from foam core sandwich composites under flexural loading were analyzed. A first core-skin debond parallel to the beam axis is considered. A static non-linear elastic two-dimensional finite element analysis of the sandwich beam is performed to evaluate the stress intensity factors at the crack tips.
