Summary

Seventeen agencies participated in a VAMAS sponsored round robin exercise on fractography of advanced structural ceramics. Topic #2 of the exercise asked the participants to characterize the fracture origins in six specimens. The results showed that the characterization scheme in Military Handbook 790 contains the necessary attributes for the complete characterization of fracture origins. However, reaching a consensus on the characterization of an origin was extremely difficult. A better characterization can be achieved by examining more than one specimen, examining the mating halves of the primary fracture surface, examining the external surface, using fracture mechanics analysis, and considering the past history of the material.
