DYNAMIC ANALYSIS OF INELASTIC PLATES BY THE D BEM/

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 associat ed elastic problem and involves not only boundary integrals but domain integrals as well. Thus boundary as well as interior elements are emp loyed in the numerical solution. Time integration is accomplished by t he explicit algorithm of the central difference predictor method. A vi scoplastic constitutive theory with state variables is employed to mdo el the material behaviour. Numerical results are also presented to ill ustrate quantitatively the proposed method of solution.
