Abstract
Stress intensity factors are determined for cracks in the form of a frustum of a cone, and loaded by a Hertzian contact pressure distribution using a global-local finite element solution. These will be helpful in interpreting blunt indentation tests quantitatively, and it is shown that for most crack geometries occurring in practice, the mode II component is about a tenth of the mode I contribution.
