The character of a piezoelectric layer bonded to an elastic substrate under static anti-plane electromechanical impacts

In engineering applications, piezoelectric materials are usually bonded to elastic substrates to form so-called smart materials and structures. Such materials and structures can respond to external electromechanical environments. This article studies a piezoelectric layer bonded to an elastic substr...

Summary:In engineering applications, piezoelectric materials are usually bonded to elastic substrates to form so-called smart materials and structures. Such materials and structures can respond to external electromechanical environments. This article studies a piezoelectric layer bonded to an elastic substrate subjected to static electromechanical loads, both of which are of finite length. A system of differential equation which own mix boundary condition is formulated in terms of the materials' physics characteristic and load character. The stress in the interface is determined by using separate variable and Fourier cosine transforms, and numerical analysis is performed and discussed. It is meaningful for research of reliability of intelligent material.
