The coefficient （ m value） of strain rate sensitivity was determined using rate sudden changing and iso-strain rate tensile test.The effects of stretching speed change and different speed changing positions on the m value determined were discussed. The results obtained show the m value determined is increased as the stretching speed is raised, The m values of different materials were measured and analyzed under same test conditions.
