Abstract：With the power-law relaxations and creeps, analysis on the experimental results of some soft tissues (i.e. cartilage, artery, ureter, mesentory etc.) was made. It was found that the power-law model could show up their mechanical properties.
Keywords：soft tissue, Power law, Relaxation modulus, Creep compliance
