Dynamic response of a FGPM hollow cylinder under the coupling of multi-fields

摘要

An analytical study for dynamic electromagnetoelastic responses of a FGPM hollow cylinder, placed in an axial uniform magnetic field, subjected to mechanical loads and electric excitations is presented. The material properties assumed to vary through the radial thickness of the FGPM hollow cylinder according to the same power law function. Based on an interpolation method, by means of finite integral transforms, the numerical results of the dynamic responses of stresses, electric displacement, electric potential and perturbation of magnetic field vector are obtained. The result of investigation may be used as a reference to solve other transient coupled problems of electromagnetoelasticity.
