Abstract

This work presents an analytical framework for magnetoelectroelastic analysis of a higher-order shear deformable sandwich cylindrical shell through a thickness-stretched model and piezomagnetoelasticity relations. The sandwich cylindrical shell is subjected to a combination multifield loadings. Based on the thickness-stretched model, the transverse deflection is decomposed into bending, shear, and stretching parts where the third term is responsible for strain along the thickness direction. The sandwich cylindrical shell is fabricated from an elastic core sandwiched by two piezoelectric/piezomagnetic face-sheets subjected to an electromagnetic environment. The multifield equations are derived using the principle of virtual work. After performing a verification study, the comprehensive numerical results are presented in terms of multifield loading. The results indicate that the radial displacement is significantly improved using the thickness-stretched model.
