BEM for general anisotropic 2D elasticity using particular integrals

Abstract

Abstract In the context of the direct boundary‐element method (DBEM) for most general two‐dimensional elastostatics, new particular integrals are presented in this paper to account for inertial and centrifugal body forces, as well as for those cases of three‐dimensional behaviour where the assumption of plane strain (or stress) may remain approximately valid despite the presence of non‐zero strain (or stress) in the out‐ofplane direction. These integrals have been implemented in a general‐purpose multi‐region boundary‐element code (namely, GPBEST) and tested via examples.
