Dynamic analysis of 3D anisotropic elastic solids by a Laplace domain BEM


This work presents a direct boundary element method (BEM) in the Laplace domain for transient dynamic analysis of the three-dimensional (3D) homogeneous linear anisotropic elastic bodies. Proposed boundary element formulation is applied together with the modified Durbin.s method for inverse Laplace transform to obtain time domain results. Implementation of the proposed method is tested by comparing the numerical results with those obtained with the finite element method software.
