Incorporation of a Vector Preisach-Mayergoyz Hysteresis Model in 3-D Finite Element Analysis

A new formulation of the Preisach-Mayergoyz model was developed to radically improve its numerical performance. This new computationally efficient vector hysteresis model was incorporated in a 3-D finite element software. Many improvements to the transient nonlinear solver were made in order to obtain a good convergence of the TEAM problem 32 while using only 125 time steps per cycle. The results of this simulation show good agreement with the experimental data.
