A new BEM formulation for tow‐ and three‐dimensional elastoplasticity using particular integras

Abstract

Abstract New two‐ and three‐dimensional boundary element formulations are developed for elastoplastic stress analysis. These new procedures differ from previous work in that volume integration is not required to incorporate the non‐linear effects in the analysis. Instead, initial stess rates are introduced in the boundary element system via particular integrals. The present formulation is implemented in a general purpose, multi‐region system, and examples are presented to demonstrate the accuracy and versatility of the method.
