Reflections on the Hysteretic Damping Model
Shock and Vibration, 2009 This paper presents a reflection on a recently proposed solution to the problem of the free vibration response with the constant hysteretic damping model, that has been presented in some conferences in recent years, by the author himself and some of his ...

Optimal design of a hysteretically damped dynamic vibration absorber
Mechanical Engineering Journal, 2020 In the optimization of dynamic vibration absorbers (DVAs), it is generally assumed that the damping force changes in proportion to the velocity of the object; this damping is called viscous damping.

An Inelastic Beam Element with Hysteretic Damping [PDF]
Shock and Vibration, 2008 In this work, an inelastic beam macro‐element that incorporates hysteretic damping is presented. Based on classical theory of plasticity, a Bouc‐Wen type model is utilized that simulates the hysteretic behavior of an inelastic spring element. Using this model, an inelastic nonlinear beam element is formulated based on the appropriate combination of two

Viscous and hysteretic damping
Bulletin of the New Zealand Society for Earthquake Engineering, 2012 Capacity design, while protecting a structure against undesirable energy dissipations, has major implications on member sizes and overall cost. Furthermore, in some situations where protected elements possess some inelastic deformation capacity, it may be unwarranted.

Modified Pyke's hysteretic model considering damping ratio
Yantu gongcheng xuebao, 2019 The damping ratio is a dynamic soil property that indicates the capacity of energy dissipation under cyclic loadings, and it plays an important role in dynamic response analysis of sites and soil-structure systems.

Non-linear modelling of elastic hysteretic damping in the time domain
Archives of Mechanics, 2020 Elastic hysteretic damping is defined as the dissipation of energy at a rate that is weakly dependent on frequency of vibration. In this article, we propose that the elastic hysteretic damping can be achieved by a simple modification to the viscous ...

STORAGE AND DAMPING OPTIMIZATION IN HYSTERETIC MULTILAYER NANOCOMPOSITES
International Journal for Multiscale Computational Engineering, 2020 Optimization of the storage modulus and the hysteretic damping capacity of multilayer carbon nanotube (CNT) nanocomposites is carried out via a differential evolution algorithm coupled with a nonlinear finite element implementation of a 3D mesoscale theory of nanocomposites exhibiting CNT/polymer stick-slip behavior.
