It is inquired about constitutive equation and forming principles of metal materials with elastic- viscoplastic properties,combined with a specific part,and discovered that the linear viscoplastic medium is just the nonlinear viscose medium under the extreme condition,the technique and testing con- ditions are also discussed in detail. Finally,the testing results are analyzed.
