材料泊松比测试方法的研究进展

Advances in Test Methods for Poisson’s Ratio of Materials

在简述材料泊松比理论计算方面进展的基础上,介绍了近年来在材料弹性行为研究中发展起来的各种泊松比的测试方法,同时分析和比较了各种测试方法的适用范围和条件。

As an important parameter in describing the elasticity of materials, the Poisson＇s ratio （u） extends into large negative or large positive values with the springing up and development of negative Poisson＇s ratio materials, which drives the further development of the theoretical calculation of u values. Simultaneously, the accurate measure of u values, which is a basic issue of such investigation, becomes much more important. This paper describes the study of the theoretical calculation of u values. Based on the testing methods of the calculation of u values in the range of the elasticity of materials, the applied range and conditions of these testing methods are compared and analyzed.
