Abstract:

Coupled multiphysics models that span multiple length scales are used to simulate the interactions among physical fields that act simultaneously. In biological and synthetic smart materials, it is often of interest to quantify the contributions of moisture, temperature, magnetic, electric, and other fields, along with their coupling effect. In this paper, we study the steadystate hygrothermomagnetoelectroelastic responses of multilayered and FG smart cylinders subjected to planar strain and stress conditions. An axisymmetric, radially polarized, and radially magnetized smart cylinder is examined under the presence of a prescribed hygrothermal field. Closed-form solutions for the governing differential equations are obtained for the cases of perfect and imperfect interfacial conditions. A discussion on the impact of multiphysics loading, bonding imperfections, heterogeneity, and non-homogeneity indices is presented via maps that help to gain insight into multiphysics response of a FG smart cylinder.
