The Green's functions discussed here are mainly the so-called half-plane solution, corresponding to a unit source within a semi-plane bounded by a flux-free straight line and an infinite plane containing internal lines of potential discontinuity. The latter is here introduced in numerical fashion, as an extension of the authors' previous numerical Green's function approach (NGF) already developed for standard fracture mechanics boundary element applications. Here, the use of such modified fundamental solutions impairs the implementation of the usual companion solutions, responsible for vanishing the fundamental potential values over the circular boundary of the LBIE internal support sub-domains. Some examples are discussed to validate the implementations.}, DOI = {10.3970/sdhm.2005.001.225} }
