Dynamic behavior of piezoelectric/magnetostrictive composite hollow cylinder

The dynamic behavior of a multilayered, perfectly bonded piezoelectric/magnetostrictive composite hollow cylinder under radial deformation is investigated. The superposition method, the state space method as well as the separation of variables method are elegantly integrated in the solution approach. The governing equations are finally transformed into two Volterra integral equations of the second kind with respect to two functions of time. The elastic, electric and magnetic fields are finally obtained according to solving the integral equations. Free vibrations and transient responses are demonstrated by numerical experiments.
