Abstract

This paper introduces a brief, although insightful, comparative analysis of the conventional, collocation boundary element method (CBEM), the hybrid stress boundary element method (HSBEM) and the hybrid displacement boundary element method (HDBEM), not only investigating the mechanical properties of the resulting matrix equations, but mainly redefining a series of concepts in both HDBEM and CBEM that hadn’t been properly considered by previous authors. This is not a review paper, but rather a theoretical investigation of three methods, with many physical considerations and some innovations that point toward mesh-reduced formulations adequate for the numerical modelling of complex problems, such as in the case of material non-homogeneity and timedependency. 1 Int
