Investigation of sensitivity of Preisach analysis for nondestructive testing

We applied the Preisach model formalism as a nondestructive material testing method to theoretical systems described by the Jiles-Atherton model. We investigated 1) the influence of stress in the model with magnetomechanical effects on a Preisach-model-based parameter and 2) the sensitivity of the parameter with respect to variation of all the Jiles-Atherton model constants and of the traditional magnetic hysteresis variables.
