Abstract

Grinding induces residual stresses and cracks at and near the surfaces of ceramic workpieces. The residual stresses in several ground ceramics are measured using the curvature method. Four point bend tests are conducted to measure the fracture strength of the ground specimens. A fracture mechanics analysis includes the measured residual stress to calculate the grinding induced surface crack size. The analysis when applied to annealed ground ferrite specimens gives evidence for crack healing. A simple empirical formula for the fracture strength of ground ceramics is obtained.
