“…It is seen that once the kernels k ij corresponding to the through cracks are determined and the part through crack profiles Lr(x l ) (or Lrl and L r2 ) are specified, the integral equations (41) and (42) (subject to conditions (43)) may be solved for fjr(t) and equations (40) and (8) or (27) would then give the stress intensity factors as functions of xl. The kernels k ij for various plates and shells containing through cracks may be found in [21], [22], [24]- [26]. For example, if we use a length parameter a* (usually a half crack length) to nonna1ize the dimensions, coordinates, and other quantities as (44) and define…”

This paper, after giving a general description of the line spring model, covers the problem of the interaction of multiple internal and surface cracks in plates and shells. The shape functions for various related crack geometries obtained from the plane strain solution and the results of some multiple crack problems are presented. The problems considered include coplanar surface cracks on the same or opposite sides of a plate; nonsymmetrically located coplanar internal elliptic cracks; and, in a very limited way, the surface and corner cracks in a plate of finite width and a surface crack in a cylindrical shell with fixed end.
