【Abstract】 The expressions of the frequencies and displacements for the axisymmetrical circular plate clamped or simply supported under the prestressed conditions are presented in mis paper. It is assumed that a simplified boundary condition may be used for the circular plate,then the convenient solution can be deduced from hankel and Laplace transforms. The response of the prestressed plates subjected to some typical transient load is discussed.更多还原
