About this document
Magnetoelastic Model for Sensors by Subhasish Dey is a document available to read on EtoBox.
This document presents a magnetoelastic model for Villari-effect magnetostrictive sensors. The model quantifies changes in magnetization of a magnetostrictive material subjected to an excitation field and stresses. It characterizes magnetic behavior using the Jiles-Atherton mean field theory for ferromagnetic hysteresis. Elastic properties are incorporated through a wave equation relating strains, stresses, and magnetization. The model yields a nonlinear PDE system describing the magnetoelastic coupling in
