EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM E646 testing. This standard covers the determination of the strain hardening exponent by tensile testing of sheet metal materials for which the plastic flow behavior conforms to the strength curve given in the introduction.
A single power curve may not satisfactorily fit the entire stress-strain curve between yield and yielding. In such a case, more than one value of the strain hardening exponent can be obtained by agreement using this test method.
This test method is specifically for metallic sheet materials that are at least 0,005 inches (0,13 mm) thick but no more than 0,25 inches (6,4 mm). The method has been successfully applied and can be applied to other forms and thicknesses by agreement.
Values stated in inch-pound units should be considered standard. Values in parentheses are mathematical conversions to non-standard SI units, provided for informational purposes only.
The value of the strain hardening exponent, n, has no units and is independent of the units used in its determination.
This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
