Steady-state analysis of a three-layered electro-magneto-elastic strip in a thermal environment

In this paper, a three-layered electro-magneto-elastic strip is investigated under a plane stress condition using finite element procedures. Two types of thermal loading, uniform temperature rise and non-uniform temperature distribution, are used. A two-dimensional rectangular element with four nodal degrees of freedom viz. thermal displacements in the x(1) and x(3) directions, and electric and magnetic potentials, is used to discretize the finite element model. The uncoupled and coupled analysis is carried out for two types of stacking sequence (B/F/B and F/B/F)under fixed-fixed and fixed-simply supported boundary conditions. Steady-state analysis is carried out to study the influence of piezo and magnetic constants on displacement, electric and magnetic potential across the thickness direction. It is found that the discontinuities of normal stress sigma(1) occur on interfaces of two dissimilar materials across the thickness direction.
