This Standard specifies the method for determining the tensile strain hardening exponent n of the sheet and strip made of metallic materials.<\/p>\n
\nThis method is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic.<\/p>\n
\nIn the case of materials with a serrated stress-strain curve in the work hardening range (materials which show the Portevin-Le Chatelier effect, such as aluminiummagnesium alloy), the automatic determination (linear regression of logarithm true stress vs. logarithm true strain,) should be used to give reproducible results.<\/p>\n
\nNOTE 1 In this Standard, the value of plastic strain is supposed to be used for the value of strain used for the calculation of the tensile strain hardening exponent.<\/p>\n
\nHowever, when the elastic strain is under 10 % of the total strain used for the calculation, the total strain may be used in place of the plastic strain.<\/p>\n
