Summary

A hybrid experimental-numerical analysis was used to study the fracture process zone (FPZ) which trailed a stably growing crack in SiCw/Al2O3 three-point bend and wedge loaded-double cantilever beam (WL-DCB) specimens. The crack closing stress versus crack opening displacement (COD) relation was determine by an inverse analysis and the fracture energy, which was dissipated at the FPZ, was found to be a large energy sink.
