Stress intensity factors are estimated for three-dimensional defects which occur in ceramic bodies. The two idealized cases considered are 1 a spherical void with a circumferential crack at its equator stressed by uniaxial tension at infinity and 2 a hemispherical pit at a free surface of a semi- infinite body also stressed by uniaxial tension with a circumferential crack at the semiequator of the pit. These stress intensity factors, which are given as a function of the crack length L to radius R of the spherical void or hemispherical pit, are considered as estimates because of the approximate nature of the analysis.
