Effect of pre-strain on compression mode properties of magnetorheological elastomers
TL;DR: In this paper, the effects of pre-strain on compression mode dynamic characteristics of both isotropic and aligned magnetorheological elastomers (MREs) are experimentally investigated considering wide ranges of particle volume fraction (15, 30, and 45%), frequency (1-30), and magnetic flux density (0-750mT) under different levels of prestrain (6, 11, and 21).

Development, optimization, and control of a novel magnetorheological brake with no zero-field viscous torque for automotive applications:
Hadi Shamieh,Ramin Sedaghati +1 more
TL;DR: The significant energy loss due to viscous torque generation in the absence of the applied magnetic field is the main obstacle in the practical realization of magnetorheological brake in the automo....
Journal ArticleDOI
Practical hysteresis model for magnetorheological dampers
TL;DR: In this paper, a new practical model is proposed to better characterize the hysteresis phenomenon in magnetorheological dampers, which considers the displacement, velocity, and acceleration excitations as well as the current excitation as input variables and includes a reduced number of constant parameters.
Journal ArticleDOI
Dynamic analysis of electro- and magneto-rheological fluid dampers using duct flow models
TL;DR: In this article, a formulation for dynamic analysis of electro-rheological (ER) and magneto rheological fluid dampers in flow and mix mode configurations under harmonic and random excitations is presented.
Journal ArticleDOI
Optimum design of structures with stress and displacement constraints using the force method
TL;DR: In this paper, a new structural analysis and optimization algorithm is developed to determine the minimum weight of structures with the truss and beam-type members under displacement and stress constraints, which combines the mathematical programming based on the sequential quadratic programming (SQP) technique and the finite element technique based on integrated force method.
