cyclic tensile loading test 循环拉伸试验
The tensile test of Q235 steel under static loading condition was done, and the stress of every level selected was tested by EMS2003 metal magnetic memory testing system.
选取Q 235钢进行静载拉伸试验，利用EMS2003型磁记忆检测系统进行各级应力水平的检测。
The experimental investigation of the effect of loading rate on the tensile properties of PC/ABS and the analysis of the test results has been given in the paper.
从简单的拉伸试验着手，研究了应变加载速率对PC/ ABS 高分子材料拉伸性能的影响，并对试验结果进行了详细分析。
The experimentation indicates that it is effective to measure the direct tensile strength and other character of concrete by change the size of the test piece and the way of loading.
通过改变试件尺寸及加载方式，还可进一步探讨采用本试验方法测量混凝土的直接抗拉强度，研究混凝土的其它性能。
