Abstract: This paper presents the theoretical analysis of a multilayered magneto-electro-thermoelastic hollow cylinder under unsteady and uniform surface heating. We obtain the exact solution of the transient thermal stress problem of the multilayered magneto-electro-thermoelastic hollow cylinder in the plane strain state. As an illustration, we perform numerical calculations of a two-layered composite hollow cylinder made of piezoelectric and magnetostrictive materials and investigate the numerical results for temperature change, displacement, stress, and electric and magnetic potential distributions in the transient state. Furthermore, the effects of the coupling, stacking sequence and position of the interface on the stresses, electric potential and magnetic potential are investigated.
