STUDIES OF THE BRITTLE BEHAVIOR OF CERAMIC MATERIALS

Abstract

The fundamental behavior of brittle nonmetallic ceramics was probed. Materials studied included poly and single crystals of MgO, BeO and two grades of Al2O3. The statistical fracture was found to be characterized by the Weibull theory. The effect of strain rates from 10 to the minus 7th power to 10 reciprocal seconds at from 75 to 1800 F on the fracture stress in bending was determined experimentally. The effects of non-uniform stress fields, of microstructure and of surface energy were investigated.
