摘要：

The residual stress intensity factor term of Vickers indentation cracks is often used to enable stable crack growth tests to be performed with ceramic materials. In the present investigation an interaction of residual and applied stress intensity factors is analysed and a relation proposed which gives a linear decrease of the residual stress term with increasing external load.
