Abstract
A boundary integral representation of the displacement field is developed and solved for the crack-opening displacement by expressing the latter on the crack surface as an expansion in localized functions, whose parametrization is determined by fitting exactly-known cross sections. Numerical results are presented for scattering of antiplane (SH) waves as a function of frequency from surface-breaking and buried 2D cracks for a variety of crack inclinations and burial depths. The theory and the method apply to the 3D case. Its numerical implementation will be straightforward but tedious.This publication has 13 references indexed in Scilit:
