Publication date:   Feb 4, 1993

Scope

The principle of the test method specified is subjecting a test piece to uniaxial tensile strain at a prescribed constant rate within the region of uniform plastic strain. It is valid only for that part of the stress-strain curve in the plastic range where the curve is continuous and monotonic. The tensile strain hardening exponent is calculated either by considering a portion of the stress-strain curve in the plastic strain region, or by considering the whole of the uniform plastic strain region.
