MEASUREMENT AND APPLICATION OF PLASTIC STRAIN RATIO r-VALUES
Plastic strain ratio r-values has been applied as one important parameter to describe the forming property of sheet specifically used for Automobile. This paper, after the measurement of samples dimensions and various deformation parameters, and the study of the influence of r-value to stamping craze rate of punched parts, shows that r-value significantly guides the production of sheets specially used for automobile.
