Modified hysteretic damping model applied to Timoshenko timber beams
Computers and Structures, 2013The present study deals with prediction of material damping in Timoshenko beams. Complex elastic moduli and complex stiffness are defined to derive an analytical model that predicts the hysteretic system damping for the whole structure. The prediction model comprises two parts, the first related to bending, and the second related to shear.

Hysteretic model and experimental validation of a variable damping self-centering brace
Journal of Constructional Steel Research, 2020ABSTRACT The variable damping self-centering brace (VD–SCB), which uses disc springs and magnetorheological fluid to re-center and dissipate energy, is a lateral force-resisting component that reduces residual deformation. This paper presents the hysteretic modeling of the VD–SCB.

Journal of Vibration and Control, 2021
The half-power bandwidth method is usually used to calculate structural damping parameters by frequency response function (FRF). In this note, the half-power bandwidth methods for the displacement FRF, the velocity FRF, and the acceleration FRF are proposed based on viscous and hysteretic damping models, respectively.

Modeling and identification of a vibration isolation system with hysteretic damping
The 2010 IEEE International Conference on Information and Automation, 2010A model to describe the hysteresis damping character of rubber isolation system is presented. It consists of a parallel spring and damper, whose coefficients change with vibration frequencies. In order to acquire these relations, a force decomposition is carried out according to some sine vibration measurement data about nonlinear forces changing with ...

Journal of Sound and Vibration, 2005
A self-excited system involving a van der Pol-type damping and a hysteretic damper representing restoring force is investigated in this paper. The influence of external force on the dynamic behavior of the hysteretic system is analyzed in detail. Numerical simulations show that, under an external force, the original hysteretic system can exhibit the so-

The Hysteretic Damping Model in Vibration Theory
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 1991The characterization of damping elements by differential or integral equations relating physical variables by transfer functions in the frequency domain and by impulse response functions in the time domain is carried out for the ideal viscous damper, the ideal hysteretic damper and the band-limited hysteretic damper.

A Complex Mode Superposition Method Based on Hysteretic Damping Model for Mode Static Correction
International Journal of Applied Mechanics, 2023Due to modal truncation, the dynamic responses calculated by the mode superposition method have some errors. In this paper, the source of truncation error of the complex mode superposition method for hysteretic damped systems with non-proportional characteristics is analyzed.

A correction to damping ratio for hyperbolic–hysteretic model for clayey soil
International Journal of Geotechnical Engineering, 2013AbstractFor clayey soils, the shear modulus and damping ratio are perhaps the two most common parameters considered in dynamic soil behavior characterization. It is well known that under cyclic loading, soil behaves hysteretically in the stress–strain plane.
