测试方法对测定金属材料屈服强度的影响及分析

Influence and analysis of testing methods on determining the metallic material yield strength

屈服强度是衡量材料力学性能的重要指标。屈服点的判定及实验速率等因素都会对材料的屈服强度测定产生较大影响。通过对实验中影响因素的分析,探讨如何更准确的测定材料的屈服强度。

The yield strength is an important mechanics performance index.The determination of yield point and the experiment factors,such as the rate of material,have great influence on the measurement of yield strength.Through the analysis on the affected factors,this paper discusses how to better determine the yield strength of the material.
