Thermodynamic admissibility of Bouc-Wen type hysteresis models
نویسندگان
چکیده
Starting from the relationship between the Bouc model and the endochronic theory and by adopting some new intrinsic time measures, the thermodynamic admissibility of the BoucWen model is proved, in the univariate case as well as in the tensorial one. Moreover, the proposed proof encompasses the cases where a strength degradation term appears. c © 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS Thermodynamics / Hysteresis / Bouc-Wen models / Endochronic theory / Seismic engineering Admissibilité thermodynamique de modèles d’hystérésis de type Bouc-Wen Résumé. Partant de la relation entre le modèle de Bouc et la théorie endochronique et grâce à l’introduction de nouveaux temps internes, l’admissibilité thermodynamique du modèle de BoucWen est prouvée, aussi bien dans le cas scalaire que dans le cas tensoriel. De plus, la preuve proposée s’applique également s’il y a un terme prenant en compte la dégradation de la force maximale. c © 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS Thermodynamique / Hystérésis / Modèles de Bouc-Wen / Théorie endochronique / Ingénierie sismique Note présentée par Pierre SUQUET S1620-7742(01)0????-?/FLA c © 2001 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS.

On the Passivity of Hysteretic Systems with Double Hysteretic Loops
The Bouc-Wen hysteresis model is widely employed to mathematically represent the dynamical behavior of several physical devices, materials and systems such as magnetorheological dampers, lanthanide zirconium or aluminum oxides, mechanical structures or biomedical systems. However, these mathematical models must account for different properties such as the bounded-input bounded-output stability,...

Despite the fact that shape-memory alloy (SMA) has several mechanical advantages as it continues being used as an actuator in engineering applications, using it still remains as a challenge since it shows both non-linear and hysteretic behavior. To improve the efficiency of SMA application, it is required to do research not only on modeling it, but also on control hysteresis behavior of these m...

In this paper, a thermodynamic analysis of Bouc-Wen models endowed with both strength and stiffness degradation is provided. It is based on the relationship between the flow rules of these models and those of the endochronic plasticity theory with damage, discussed in a companion paper (Erlicher and Point, 2007). Using the theoretical framework of that extended endochronic theory, it is shown t...
