Behaviour Investigation of SMA-Equipped Bar Hysteretic Dampers Using Machine Learning Techniques
Applied Sciences (Switzerland), 2021 Most isolators have numerous displacements due to their low stiffness and damping properties. Accordingly, the supplementary damping systems have vital roles in damping enhancement and lower the isolation system displacement. Nevertheless, in many cases,

Applied Sciences (Switzerland), 2017 Relative wavelet energy entropy (RWEE) is proposed to detect and quantify damage to hysteretic dampers used for the passive seismic control of building structures. Hysteretic dampers have the role of dissipating most of the energy input of an earthquake.

A Loss Separation-Based Dynamic Jiles–Atherton–Bingham Model for Magnetorheological Dampers [PDF]
SensorsMagnetorheological (MR) dampers exhibit significant hysteretic nonlinearities, particularly under dynamic operating conditions, where accurately modeling the complex coupling between magnetic flux density and excitation current remains challenging.

Efficiency of hysteretic damper in oscillating systems [PDF]
Mathematical Modelling of Natural Phenomena, 2020 This paper is dedicated to comparative analysis of nonlinear damping in the oscillating systems. More specifically, we present the particular results for linear and nonlinear viscous dampers, fractional damper, as well as for the hysteretic damper in linear and nonlinear (Duffing-like) oscillating systems.
