Abstract

This paper presents a numerical method for modeling magneto-mechanical energy harvesting devices. Our existing energy-based
single-valued (SV) magneto-mechanical material model is utilized for the first time in a 2-D finite element formulation for an energy-
harvesting application. The SV material model yields the magnetic field strength as a function of strain and magnetic flux density. The
proposed method can predict the voltage induced in a pickup coil due to inverse magnetostriction, when the test sample is subjected to
dynamic loading. The results from the numerical method are experimentally verified using a prototype energy harvester.
