Ajb. Tadeu et al., Closed-form integration of singular terms for constant, linear and quadratic boundary elements. Part 2. SV-P wave propagation, ENG ANAL, 23(9), 1999, pp. 757-768
Part I of these two related papers considered the analytical evaluation of
singular integrals for anti-plane boundary elements, the results of which w
ere then applied to the evaluation of scattering problems involving SH wave
s. This second part provides an extension of these results to the more comp
licated case of in-plane boundary elements, and presents their application
to scattering problems involving SV-P waves. First, the singular integrals
for constant, linear and quadratic boundary elements are evaluated a in clo
sed form. Thereafter, the formulation is used to model cylindrical inclusio
ns in a two-dimensional elastic medium illuminated by dynamic in-plane (pla
ne-strain) line sources. The boundary element method (BEM) results are then
compared with the known analytical solutions for these problems. (C) 1999
