Boundary Element Analysis for Dynamic Loading of a Circular Plate on an Elastic Medium

摘要

The behavior of a circular plate on an elastic medium and the applicability of the boundary element method to solving the problem were studied. The loading can be dynamic or static. The dynamic problem was solved in the frequency domain by the Fourier transform technique. Equations based on the direct and indirect boundary element methods were derived for a plate on a one or two-parameter elastic medium. Computer programs based on the direct and indirect boundary element methods were developed. Examples presented relate to the behavior of the foundation plate of a nuclear power plant. The study shows that the boundary element method is applicable to the static and dynamic analysis of a plate on an elastic medium.
