Abstract

A coupled model is developed to calculate mechanical deformation of magnetic materials in a magnetic field. The two equations governing magnetic and mechanical phenomena are solved simultaneously using the finite element method. The magnetic force distribution is calculated through a local application of the virtual work principle. The saturation of the material is considered. The nonlinear coupled system is solved by the Newton-Raphson method and the whole matrix is symmetrized. An example is given showing the effectiveness of the model.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
