GB/T 228.1-2010中金属材料拉伸试验速率控制方法的分析

Analysis on Rate Control Method of Metal Material Tensile Test of Standard GB/T 228.1-2010

摘要: 通过两组拉伸试验分析了不同试验阶段及试验数据特性、试验过程的速率控制方法及其对试验数据的影响，研究了位移速率控制方法在试验过程中的控制状态，为相关试验人员合理选择试验速率控制方式提供参考。

Abstract: Different test stage, the test data feature, test rate control method and its influence on the test data were analyzed through two groups of tensile tests. The displacement rate control method was researched, to provide the laboratory technician with reference of the reasonable control mode selection.
