摘要：

We have used loads typical in indentation tests (294 N) and examined the response in materials with different fracture toughnesses. The materials examined included one type of alumina and two types of zirconia. In each sample an indentation was made using a Vickers indenter, the sample was dyed, the values of c and a were measured, and the sample was broken in a three-point bend. The crack profile was determined from a microscopic examination of the distribution of dye in the body of the sample.
