    WK34111

    1. Rationale

    Revision of E646-07 Standard Test Method for Tensile Strain-Hardening Exponents (n -Values) of Metallic Sheet Materials is necessary becausea)it confuses total strain with plastic strain,b)the procedure for subtracting elastic strain is vague, and c)there is no requirement to report type of strain used to get n. d)ISO has eliminated n based on total strain.
