✦ Synopsis

The dynamic response of elastic panels subjected to pressure loadings by shock waves is investigated. Accurate approximate solutions for the time-history response (displacement as well as strain) are obtained for the cases of both simply supported and completely clamped panels of various polygonal boundary shapes. The transient behaviour is discussed by using the isoamplitude contour lines method in conjunction with the normal mode method. The analyses derived here have technical applications in the estimation of window, wall panel or fiat roof response to a sonic boom or to explosion blast waves. All details are explained by graphs. Some comparison is made with previously obtained results wherever available.
