Abstract

An analytical solution for the problem of time-dependent stress redistribution of a piezomagnetic rotating hollow cylinder subjected to an axisymmetric thermo-magneto-Electro-mechanical loading is derived for the condition of plane strain. A differential equation containing creep strains is found using the constitutive equations, equilibrium equation and solving heat equation in plate strain. In the first step, eliminating creep strains in the differential equation, an analytical solution for the differential equation is obtained. Then, by adding creep strains and assuming constant thermal conditions, the creep stress rates and electric and magnetic potential are obtained using solving a differential equation. Lastly, the history of stresses, radial displacement, magnetic potential, and electric potential during the time can be obtained using an iterative method. In the numerical examples, the effects of time passing on the structure behavior and the effective parameters such as thermal boundary condition, angular velocity, and Electromagnetic boundary condition were investigated comprehensively.
