主　　题：Cut-out Magneto-electro-elastic Natural frequency Higher order shear deformation Coupling 

摘      要：This article deals with investigating the effect of cut-outs on the natural frequencies of magneto-electroelastic(MEE)plates incorporating finite element methods based on higher order shear deformation theory(HSDT).In order to consider the influence of cut-out,the energy of the cut-out domain is subtracted from the total energy of the entire *** governing equations of motions are derived through incorporating Hamilton’s principle and the solution is obtained using condensation *** proposed numerical formulation is verified with the results of previously published literature as well as the numerical *** addition,this research focuses on evaluating the effect of geometrical skewness and boundary conditions on the frequency *** influence of cut-outs on the degree of coupling between magnetic,electric and elastic fields is also investigated.
