The Penny-Shaped Crack
Chapter
Abstract
As in the two-dimensional case, we shall find considerable similarities in the formulation and solution of contact and crack problems. In particular, we shall find that problems for the plane crack can be reduced to boundary-value problems which in the case of axisymmetry can be solved using the method of Green and Collins developed in §22.2.

In the general case, we obtain a two-part boundary-value problem for the half-space z > 0, in which conditions (23.6) and (23.7) are to be satisfied over A and Ā respectively, where Ā is the complement of A in the plane z = 0.Google Scholar
