Abstract
In order to clarify the effect of specimen thickness on strength degradation in ceramics, Al_2O_3 sphere impact and indentation tests were carried out on Al_2O_3+TiC specimens. The sphere were 5/32inch in diameter and the specimen thickness were 2.0,3.6 and 9.0mm. After the impact or the indentation tests, the residual strength was measured by a four-point bending test. The residual strength decreases with an increase in the impact speed or the indentation load. In the case that the cone crack was related to the final fracture, the residual strength was estimated. As a result, it was seen that the estimated values of residual strength were in approximate agreement with the experimental values.
