3D fracture analysis by the symmetric Galerkin BEM. (English) Zbl 1010.74078

Summary: The subject is the formulation and implementation of symmetric Galerkin BEM for three-dimensional linear elastic fracture mechanics problems. A regularized version of displacement and traction equations in weak form is adopted, and the integration techniques utilized for the evaluation of double surface integrals appearing in the discretized equations are detailed. By using quadratic isoparametric quadrilateral and triangular elements, we solve some example crack problems to assess the efficiency and robustness of the method.
