标准简介

This document specifies the principle, test pieces, test equipment, test conditions, determination of properties and test report for the determination of the modulus of elasticity and Poisson's ratio of metallic materials by the static method and the dynamic method. The static method part of this document is applicable to the determination of the Young's modulus, chord modulus, tangent modulus and Poisson's ratio of metallic materials in the elastic state by uniaxial tension and compression at room temperature. The determination of the Young's modulus, chord modulus, tangent modulus and Poisson's ratio at other temperatures may also be carried out with reference to this document. The dynamic method part of this document is applicable to the determination of the dynamic Young's modulus, dynamic shear modulus and dynamic Poisson's ratio of homogeneous metallic materials at temperatures between −196 °C and 1 200 °C by the energy coupling method and the impulse excitation method. The determination of the dynamic Young's modulus, dynamic shear modulus and dynamic Poisson's ratio of other homogeneous and isotropic solid materials at other temperatures is carried out with reference to thi
