Název v původním jazyce

Divergence based damage assessment of hysteretic materials

Popis výsledku v původním jazyce

The mechanical properties of hysteresis materials are evaluated by the Preisach-Mayergoyz model (PM model). Software called 'PM identificator' with it's main function, automatic identification of the PM space probability density within a class of distribution mixtures by means of optimization stochastic algorithms and phi-divergence measures, is presented. We focus especially on the Hellinger distance, the so called LeCam divergence, and L2-distance. An extension of Simulated Annealing was proposed and implemented methods were tested with respect to time, reliability and accuracy of the solution found. In uence of parameters of each algorithms and divergence criterions are tested. Both, index of elasticity and index of damage, based on identified PM space of hysterons of hysteretic material by means of nonparametric methods, were defined. Experimentally measured data were completely processed.
