Elastodynamic thin plate bending analysis by boundary element method with Laplace transform

摘要

The boundary element method(BEM) is developed for the dynamic analysis of thin elastic plate bending problems with arbitrary boundary conditions. The formula- tion employs Laplace-transform technique where the boundary integral equations are obtained on the Laplace transformed domain with the fundamental solutions derived from Kelvin's functions. The accuracy of the numerical results mainly depends on those of numerical estimation of the singular integral derived form the static term of the fundamental solutions.
