Abstract

In this work a formulation of boundary element method is developed for the treatment of transient dynamic anisotropic problems using elastostatic fundamental solution. The inertia effects appear in the formulation as body forces. The dual reciprocity boundary element method is used to transform the domain integral into a boundary integral. The numerical results for a quasi-isotropic problem showed good agreement with the equivalent prob- lem obtained with Kelvin's isotropic solution. When an anisotropic problem is treated, the results showed stability for many cycles. 1 Introduction Presently the use of boundary element method (BEM) has increased in the most different areas. For isotropic transient problems the BEM has already been proved to be a capable method for model- ing wave propagatio
