APPLICATION OF THE BOUNDARY ELEMENT METHOD FOR ANALYZINGTHE DYNAMICS OF ANISOTROPIC ELASTIC BODIES

A boundary-element scheme for numerically modeling the dynamics of 3-D anisotropic elastic bodies is presented. A direct version of the boundary integral equation method is used in combination with the time integral Laplace transform. Kernels of boundary integral equations are constructed using combined interpolation-direct computation. The boundary-element model uses a matched approximation and the collocation method. Examples of boundary-element analyses are presented and compared with the results of other authors. Keywords: boundary element, three-dimensional problems, dynamics, anisotropy, elasticity.
