Abstract	BARRETTO, Saulo F. A. E/astodynamic analysis of plates, using the Boundary Element Method, with soil-structure interaction. São Carlos , 1995. 115p. Tese (Doutorado) Escola de Engenharia de São Carlos, Universidade de São Paulo. The combination of the boundary element and the finite element methods is the usually employed procedure to analyse plates in the bending interacting with the supporting soil. By using the association of both methods one can take the advantage of each method and consequently reach an improved technique to deal with practical problems. However, the FEM formulation can not represent well the stress and effort concentrations along the boundary, that may occur due to the higher plate stiffness when compared with the soil media, as the BEM technique does. Therefore, the plate bending on elastic foundation is proposed here using only BEM formulations, i.e. both the three-dimensional and the plate problems are formulated by boundary formulations for the elastostatic and elastodynamic cases. Two different ways to deal with the elastodynamic plate bending problem are discussed, emphasizing possible numerical instabilities that those techniques may exhibit. Finally, after proposing the combination of the three-dimensional and plate problems, results of numerical examples presented to show the advantages and disadvantages of the proposed technique.
