英文摘要：

The response histories and distributions of transient stresses, displacement of asymmetric electrostrictive structures subjected to a sudden electrical shock were studied. Exact solutions for transient displacement and stress fields in the solid cylinder were determined by using Laplace and Hankel transform techniques. Numerical results were also presented and graphically shown. It is found that the transient displacement and stress would be significantly large in magnitude when electrical loading is applied. Furthermore, the technique for solving the asymmetric problem is applicable to the cylindrical problem of other materials.
