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.

拉伸和压缩模量不同的各向同性物体的弹性理论的控制方程的实验研究和验证的方法学问题

摘要

本文涉及各向同性物体在不同来源和结构的固体样品的拉伸和压缩试验中的多模量线性弹性模型的方法学和实验验证。我们分析了拉伸压缩试验中记录的杨氏模量值不同的原因。结果表明，使用适当的测试技术和设备来测量和记录均质单轴应力状态下的变形，对于许多承受拉伸和压缩载荷的材料，有可能获得杨氏模量的统计上无关紧要的差异。
