Dynamic response of a pyroelectric hollow sphere under radial deformation

摘要

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.
