Transient response of a general anisotropic solid to dislocation growth: alternative formulation

The response of an unbounded homogeneous general anisotropic solid to dislocation growth can be obtained from a convolution of the body force equivalent of the dislocation with the Green’s function. This work considers the transient case of a surface of discontinuity in displacement that expands with time from a point source. The expansion rate is subsonic, but largely arbitrary otherwise. The surface need not be planar, and if so, need not lie in a principal material plane. Some differences in procedure from related studies are noted. The solution expressions use a dislocation description in terms of surface geometry, and have a hybrid but somewhat more explicit form.
