ABSTRACT
Solutions of some advanced problems are discussed in this chapter and relevant references are given.
In all crack problems considered so far the crack is assumed to have a sharp edge and a smooth front in the crack plane. Four different crack geometries are shown in plan views A, B, C, and D in Figure 10.1. Note that in the elevation view all four cracks look similar-a crack of length 2a. Out of these four cracks so far we have discussed the solutions of crack geometries A (Griffith crack) and B (elliptical crack). No discussion on the stress field variation near the crack corners as shown in problem geometries C and D has been presented in previous chapters. This problem has been solved by Xu and Kundu (1995).
