✦ Synopsis

A direct boundary element method is developed for the dynamic analysis of thin inelastic flexural plates of arbitrary planform and boundary conditions. It employs the static fundamental solution of the associated elastic problem and involves not only boundary integrals but domain integrals as well. Thus boundary as well as interior elements are employed in the numerical solution. Time integration is accomplished by the explicit algorithm of the central difference predictor method. A viscoplastic constitutive theory with state variables is employed to mdoel the material behaviour. Numerical results are also presented to illustrate quantitatively the proposed method of solution.

The plate may have arbitrary shape and its boundary may be subjected to any type of boundary conditions. The non-uniform thickness of the plate is an arbitrary function of the coordinates x, y.

The reduction of stress concentration around a circular hole in a dynamically loaded plate by introducing auxiliary holes around the original hole is studied numerically. The solution of this plane stress problem is carried out in the Laplace transformed domain with the aid of the boundary-element m
