Abstract

Magnetoelectric (ME) materials have presented themselves appealing towards sensing and energy harvesting applications. Comprehensive studies under linear and nonlinear material behavior have been performed on symmetric ME laminates subjected to homogeneous deformations. However, studies on unsymmetric laminates working under bending action are sparse, despite their advantages like low resonant frequencies. A finite element (FE) model is thus developed in this work based on Mindlin plate theory to quantify the ME coupling under an applied magnetic loading in quasi-static and resonant conditions. Due emphasis has been given to the material nonlinearity of the ferromagnetic phase and the resulting ME coupling in bending and axial as well as torsional modes has been studied. The influence of the frequency of applied AC magnetic field, the magnitude of the bias field and their orientation relative to the plate axes and the effect of plate width are explored for free-free and cantilever conditions. The developed model is also validated against data available in literature. The results illustrate that the cantilever configuration offers a two-fold advantage of high ME coupling and low resonant frequency.
