ELECTROMAGNETOELASTIC SOLUTION OF A ROTATING FUNCTIONALLY GRADED PIEZOELECTRIC HOLLOW CYLINDER

摘要

In this article, the analytical solution of a rotating radially polarized functionally graded piezoelectric hollow cylinder is investigated. The cylinder is placed in a constant magnetic field and is subjected to the electro-mechanical loading. All material properties are taken to follow a power law along the radial direction of the cylinder. The two coupled differential equations in terms of the displacement and electric potential with those effects of the magnetic field are solved directly. Numerical results are given to illustrate the effects of non-homogeneity, angular velocity, magnetic field, and different boundary conditions on the electromagnetoelastic behavior of the hollow cylinder.
