Abstract

The aim of this work is to present an elastodynamic coupling of a plate in bending with the three-dimensional soil medium by using the Boundary Element Method formulation. This scheme is adopted in order to better represent some aspects of this kind of structural system, as for instance, the stress concentration. The formulation used to treat the soil media is based on time domain fundamental solution, while the dynamic behavior of the plate in bending is represented making use of the mass matrix approach. 1 Introduction The coupling of any structure with the soil medium is usually idealized by using the Finite Element Method (FEM) and the Boundary Element Method (BEM) formulations, respectively. Thus, one can take the advantages that each method presents to treat each partic
