Thermodynamic admissibility of Bouc–Wen type hysteresis models
[Admissibilité thermodynamique de modèles d'hystérésis de type Bouc–Wen]
Comptes Rendus. Mécanique, Volume 332 (2004) no. 1, pp. 51-57.

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 Bouc–Wen 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.

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 Bouc–Wen 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.
