摘要：
Analytical studies on electromagnetoelasticbehaviors are presented for the functionally graded pie-zoelectric material (FGPM) solid cylinder and sphereplaced in a uniform magnetic field and subjected tothe external pressure and electric loading.When themechanical,electric and magnetic properties of thematerial obey an identical power law in the radial direc-tion,the exact displacements,stresses,electric potentialsand perturbations of magnetic field vector in the FGPMsolid cylinder and sphere are obtained by using the infin-itesimal theory of electromagnetoelasticity.Numericalexamples also show the significant influence of materialinhomogeneity.It is interesting to note that selecting aspecific value of inhomogeneity parameter β can opti-mize the electromagnetoelastic responses,which willbe of particular importance in modern engineeringdesigns.
