This work presents the Bodner-Partom and Perzyna constitutive law to describe a dynamic behaviour of magnetorheological damper. Those laws usually used for metals, are presented here for shear stresses to express viscoplastic properties of MR fluid. We determine parameters for fluid in the damper prototype that are required for the Bodner-Partom and Perzyna models. Experimental results are later compared with numerical results.
