Experimental investigation of creep and recovery behaviors of magnetorheological fluids

摘要: Creep and recovery behaviors of a magnetorheological (MR) fluid under constant stress shear were investigated. This experiment was accomplished by using rheometer with parallel-plate geometry. The applied ranges from small value to big one which approaches the yield stress. effects magnetic field strength temperature on creep behavior addressed. experimental results indicate that MR fluids behave as linear viscoelastic bodies at stresses; increasing stresses, nonlinear viscoelastic, viscoplastic, or purely plastic properties will dominate. Hence, predominantly elastic stresses high stresses. Moreover, are explained typically thick column structure.
