摘要：

Delamination cracks in composites may interact with misaligned or inclined fibers. Such interactions often lead to fiber bridging, which causes the nominal delamination resistance to increase as the crack "tends. Substantial specimen geometry effects are also involved. An experimental investigation of the role of fiber bridging has been conducted for three different composites. The results are compared with fiber bridging models based on a softening traction law, leading to schemes for predicting trends in delamination resistance with specimen geometry and crack length. Implications for utilizing this effect to suppress the growth of delaminations are presented.
