Comparison of the differential equation accommodation model with experiment

Abstract

A differential equation accommodation model, which we previously presented based upon the Preisach model, has been modified so that changing the accommodation constant, β, does not affect the major loop. This has the dual advantage that identification of the model parameters is easier and also ensures that an accommodating minor loop does not go outside the major loop. The modified model permits detailed comparison with experiment. There was a remarkable agreement between the model and previously published experimental data.

“…The minor loops are attached to the descending branch of the major loop. Model validation on this data is carried out in [4], [12], and [14]. The presented results show that models with a different basis are capable of describing the presented measurements.…”

“…In [4] these two models are combined to capture accommodation. An extension to Preisach models is developed in [8], [10], [11], and [12].…”
