“…Changes of two or three orders of magnitude may occur in the yield stress and apparent viscosity, as well, the suspension system changes from Newtonian liquid to non-Newtonian liquid when a magnetic field was applied to MR suspensions [2][3][4][5][6][7][8].…”

The damping property of magnetorheological (MR) elastomers is characterized by a modified dynamic mechanical-magnetic coupled analyzer. The influences of the external magnetic flux density, damping of the matrix, content of iron particles, dynamic strain, and driving frequency on the damping properties of MR elastomers were investigated experimentally. The experimental results indicate that the damping properties of MR elastomers greatly depend on the interfacial slipping between the inner particles and the matrix. Different from general composite materials, the interfacial slipping in MR elastomers is affected by the external applied magnetic field.

“…It is well known that the highly controllable damping force of the MR damper is originated from the magnetized particle chains formed in the MR fluids upon exposure at an external magnetic field Bossis et al 2002Bossis et al , 2003. The mechanism responsible for the controllable shear stress is that magnetized particle chains could be formed and could resist shear stress in the direction perpendicular to the magnetic field to some extent.…”

This paper is an extended study on the model of the hysteretic dynamics of magnetorheological dampers based on a phenomenological phase transition theory (Wang and Kamath in Smart Mater. Struct. 15(6): [1725][1726][1727][1728][1729][1730][1731][1732][1733] 2006). It is demonstrated that, by appropriately choosing model parameters, the frequency dependence of the hysteretic dynamics can be captured very well by the model based on phase transition theory. Whilst by introducing an appropriate rescaling coefficient to account for the strength of the magnetized particle chains with various magnetic field strengths, the field strength dependence of the hysteretic dynamics can also be captured very well by the same differential equation with the same set of model parameters. There are in total eight model parameters introduced for capturing the hysteretic dynamics, including its dependence on the loading rate and field strength.

“…These fluids are suspension of micro sized, magnetisable particles in an appropriate carrier fluid. However, in the presence of an applied magnetic field, the iron particles acquire a dipole moment aligned with the external field which causes particles to form linear chains parallel to the field (De Gans et al, 1999;Chin et al, 1999;Kordonskii et al, 1999;Bica, 2006a;Bombard et al, 2007;Pu et al, 2006;Bossis et al, 2003) as shown in the Fig. 1.…”

The main aim of this study is to synthesize magneto-rheological fluid in laboratory using silicon oil as carrier oil and it is mixed with variation in concentration of iron particles of size around 4-9 µm, fine lithium grease is used as surfactant. Prepared MR fluid is tested under plate and cone type rheometer for finding is rheological properties like shear stress, shear rate, shear viscosity, storage modulus and loss modulus.
