Estimation of the magnetoelectric coefficient of a piezoelectric-magnetostrictive composite via finite element analysis

Abstract

We proposed a new approach for estimating the magnetoelectric coefficient of magnetostrictive/piezoelectric composites via finite element analysis. With this method, the relationship between inputting magnetic field and outputting electric polarization for magnetoelectric composites could be directly calculated. This method offers efficient calculation and is applicable for magnetoelectric composites with any complex structures without restrictions on their connectivity and structures. As examples, the magnetoelectric coefficients of 1-3 type and 0-3 type composites were calculated and the results were found to agree well with literature data.
