A HARMONICALLY EXCITED ELASTIC HALF-PLANE CONTAINING A RIGID FLAT INCLUSION

The plane strain problem for an elastic half-plane containing a rigid flat inclusion and subjected to a concentrated harmonic surface load i s considered. The problem is reduced to a system of singular integral equations, with the differences in interface stresses between the incl usion and the matrix as the unknown functions. With the potential appl ications to problems in fracture mechanics and the non-destructive tes ting and evaluation in mind, the main results presented are the modes I and II stress intensity factors and the components of the displaceme nt vector on the surface.
