METHODOLOGICAL PROBLEMS IN EXPERIMENTAL STUDIES AND VERIFICATION OF THE GOVERNING EQUATIONS OF THE THEORY OF ELASTICITY FOR AN ISOTROPIC BODY WITH DIFFERENT MODULI IN TENSION AND COMPRESSION

Abstract

The paper is concerned with methodological and experimental verification of multimodulus linear elasticity model for an isotropic body during tension and compression tests of solid samples of different origin and structure. We analyze the reasons why the values of Young’s modulus recorded during tension–compression tests are different. It is shown that using appropriate test techniques and equipment for measuring and recording deformations in a homogeneous uniaxial stress state makes it possible to obtain statistically insignificant differences in Young’s modulus for a number of materials subjected to tensile and compressive loads.
