Abstract
Residual stresses are introduced into the surface region of ceramics during abrasive grinding. The presence of the residual stresses can affect the strength of the ground specimens. In the present study, a methodology is proposed to determine the contribution of the residual stresses to the strength of the ground specimens. The method uses Weibull statistics to evaluate the crack size distribution before and after annealing. If the crack size distribution is not changed after annealing, the amount of the strength reduction is attributed to the effect of residual stresses as verified by direct measurements of the residual stress at the surface.
