✦ Synopsis

The dynamic response of a pyroelectric hollow sphere under radial deformation is considered. By virtue of the separation of variables method, it is transformed to a second kind Volterra integral equation about a function with respect to time, which can be solved by using the interpolation method. Then the expressions for displacements, stresses, electric displacements and electric potential can be obtained. The present method is suitable for the hollow sphere with an arbitrary thickness subjected to arbitrary symmetric thermal loads. Numerical results of thermally shocked hollow sphere are also presented.

The dynamic response of orthotropic circular cylindrical shells subjected to exponentially decaying uniform radial pressures are considered. The initial values of the pressures applied are slightly larger than the corresponding static collapse pressures of the shells obtained on the basis of Tresca'

The effective stiffness theory which represents a layered composite as a higher order continuum with microstructure is employed to describe the linear as well as the non-linear dynamic response of a laminated plate. The plate is subjected to normal time-dependent tractions in the direction of the la
