IS 2854 : 1990 Determination of young's modulus,tangent modulus and chord modulus - Test method

1 Scope

1.1 This standard covers method for determination of Young'smodulus, tangent modulus and chord modulus of structural materials.This method is limited to materials in which temperatures andstresses at which creep is negligible compared to strain producedimmediately upon loading and to elastic behaviour.

1.2 Because of experimental problems associated with theestablishment of the origin of the stress-strain curve described in7.1, the used of either initial tangent modulus (that is, the slopeof the stress-strain curve at the origin) or secant modulus is notrecommended and their determination is outside the scope of thismethod.
