Abstract

Abstract:

With the growing application of piezoelectric materials,the characteristic analysis of piezoelectric materials is taken more and more seriously. For the natural frequency analysis of functionally graded materials,the Solid 98 element in the ANSYS 12.0 and the parameter designing of APDL language are adopted,supposing that the characteristic parameters of the material change along with the thickness of the plate. The gradient change about characteristic parameters of piezoelectric material is realized,and natural frequency of the functionally graded piezoelectric laminate is analyzed.

Key words: functionally gradient, piezoelectricity, ANSYS, natural frequency
