A Laplace domain BEM formulation for dynamic problems of anisotropic elasticity

Abstract eng:
This paper presents a Laplace domain direct boundary element formulation for three-dimensional problems of linear anisotropic elasticity, based on the integral representations of the dynamic fundamental solutions. Special technique for approximation of both static and dynamic parts of the displacement fundamental solution (and its spatial derivative) over the boundary elements is employed along with a parallelization scheme in order to improve computational efficiency. Modified Durbin’s method is used to obtain time domain solutions. To validate the proposed formulation numerical results are compared with results of dynamic experiment and finite element solutions.
