Abstract
A theoretical technique is developed for determining both KI and KII from influence functions for angled edge cracks subjected to arbitrary distributions of normal and tangential contact stresses. Numerical results are presented which indicate the effect of crack length and crack angle on four influence functions, from which KI and KII can be readily determined for specified distributions of tangential or normal contact stresses. In order to illustrate the use of the influence functions, a worked example is presented which shows the variation of KI and KII with crack length and crack angle calculated for an assumed parabolic distribution of tangential stress under a fretting pad. Corresponding values of KI and KII for other distributions of tangential and normal stresses may be determined by the same simple summation techniques used in this report.
