Static Electric Force and Measurement Principle of Material Constants in Electrostrictive Material

الملخص EN

Electrostrictive materials convert electrical energy into mechanical energy and vice versa.

They are extensive applied as intelligent materials in the engineering structures.

The governing equations in electrostrictive media under the quasistatic electric field are very important for the measurement of material constants and the research on the strength and function.

But some theoretical problems should be further clarified.

In this paper, the electric force acting on the material is studied and the complete governing equations will be given.

In this paper a possible method to measure electrostrictive coefficients is also discussed.
