本文有效地解决了拉伸-蠕变-循环复合加载试验中几项关键性的测试技术问题,试验过程中控制方式的动态转换、用载荷控制来实现蠕变加载下的恒应力控制和试验原始数据的采集问题。这些试验条件的建立,使得研究内蕴时间塑性本构关系的复合加载试验得以实现
This paper effectively solved the tensile - creep - cyclic composite loading test of several key test techniques, the control process during the test of dynamic conversion, with load control to achieve the creep loading of the constant stress control and test the original Data collection problems. The establishment of these experimental conditions makes it possible to study the composite loading test of the intrinsic plastic time-dependent constitutive relationship
