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 scientifique...

To accurately characterize the mechanical behavior of magnetorheological elastomer (MRE) under a wide range strain amplitude, excitation frequency, and magnetic field, viscoelastic fractional derivative was introduced, modified Bouc-Wen model based on for MRE in nonlinear region established. The can describe hysteretic characteristics region, but it cannot simulate magneto-viscoelasticity frequ...
