Abstract

Present paper describes a development of the method of eigenfunction expansion to the impact response analysis of anisotropic plates based on the theory of elastodynamics. The elastodynamic solution is decomposed into their quasi-static and dynamic components. The quasi-static solution is obtained by an exact analy- sis of the quasi-static differential equations with the time-dependent boundary con- ditions under the given impact pressure loading. The dynamic part is given in an infinite series of the eigenfunctions (normal modes) which are derived from the free vibration analysis of the associated problem satisfying homogeneou
