Resumen
This document specifies a method for determining the tensile strain hardening exponent n of flat products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic (see 8.4).
In the case of materials with a serrated stress-strain curve in the work hardening range (materials which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys), the automatic determination (linear regression of the logarithm true stress vs. the logarithm true plastic strain, see 8.7) is used to give reproducible results.
