Název v původním jazyce

Structural identification of statistical distribution in Preisach-Mayergoyz hysteron space

Popis výsledku v původním jazyce

Hysteresis is a phenomenon occurring in ferromagnetic materials as well as in a course of deformation of some materials, which are flexible or elastic. Preisach-Mayergoyz model (PM model) of hysteresis has an important place in the field of nonlinear elastic spectroscopy. The model can be used to structure detection of hysteresis materials. To identify the density of hysterons in PM space the iterative optimization method called simulated annealing was used. We focused on the mixtures of distributions due to these might comply with the structure of real materials. Experimentally obtained data of porcine skin tissue provided by laboratory INSA in Blois, France were processed. For easier and less time-consuming identification there were made an effort both to estimate the number of components of distribution mixture from the primary analysis of hysteresis curve and to ascertain the impact of pollution on the shape of hysteresis curve.
