Abstract The Symmetric Galerkin Boundary Element Method is advantageous for the linear elastic fracture and crackgrowth analysis of solid structures, because only boundary and crack-surface elements are needed. However, for
engineering structures subjected to body forces such as rotational inertia and gravitational loads, additional domain
integral terms in the Galerkin boundary integral equation will necessitate meshing of the interior of the domain.
In this study, weakly-singular SGBEM for fracture analysis of three-dimensional structures considering rotational
inertia and gravitational forces are developed. By using divergence theorem or alternatively the radial integration
method, the domain integral terms caused More >
