An Extended Method Solution for a Pulse Loaded Thin Plate

摘要

This paper deals with a new extension of a weighted residual method of analysis called the extended field method. The extended field method is applied for the first time to the problem of the transient vibration of a uniformly thin elastic plate. Numerical results have been obtained which validate the analysis procedure and show better solution convergence that is obtainable by standard methods of analysis for the same number of degrees of freedom. Further studies are necessary to obtain still better convergence. (Author)
