Description

This work presents a novel method to obtain a B-spline surface based Everett map, for application in the Preisach model of hysteresis, to predict static hysteresis behavior in NO27-1450H motor steel. The novelty of the method stems from its ability to directly capture the Everett map as a closed-form B-spline surface expression, while simultaneously eliminating model artifacts that plague Everett map based Preisach models. Contrary to other works, that applied numerical descriptions for the Everett map, the presented approach is of completely analytic nature. In this work the B-spline surface fitting procedure and the necessary constraints are explained. Furthermore, the B-spline based Everett map was validated by ensuring that any physically meaningless artifacts were properly eliminated. Additionally, the model output was comparing to a measured arbitrary benchmark excitation, which it was able to reproduce with high accuracy.
