Abstract

The three-dimensional elastostatic problem of an arbitrarily oriented planar crack of general shape penetrating through a bimaterial interface is considered. Use is made of the body force method to derive the two-dimensional boundary integral equations which are then solved numerically. The solution yields the three crack opening displacements in the crack domain as well as the three modes of stress intensity factors along the crack contour. Numerical results are given for a penny shaped crack symmetrically oriented with respect to the interface under uniform normal pressure for various angles of inclination to the interface.
