Summary

The applied moment double cantilever beam (AMDCB) method of toughness measurement was modified by development of Lshaped arms to inhibit delamina-tion of ceramic fiber and other anisotropic composites. Analytical and experimental evaluation of the method show it to be accurate; it also significantly reduces specimen preparation time.
