Abstract : Research has been conducted on toughening mechanisms, machining and surface damage, thermal shock and general aspects of fracture in ceramic materials. Quantitative models of the various fracture processes have been developed. Special emphasis has been placed on the toughening that occurs in the presence of microcracks. (Author)
