1.
It is vital to obtain dynamic stress equilibrium and a nearly constant strain rate over most of the test duration.
大直径分离式霍普金森压杆(SHPB)试验装置被越来越多地应用于混凝土等脆性材料的高应变率力学性能研究,试件在破坏前,满足应力均匀分布要求,且保持恒应变率加载,是保证SHPB试验有效性及试验结果可靠性的关键。
2.
The contratest results shows that for the brittle and low mechanical impedance materials,conventional SHPB experiment does not meet the precondition that the samples loaded dynamically with a SHPB apparatusshould be in dynamic stress equilibrium over the test duration, therefore, the experiment is invalid.
实验采用了两种不同的加载技术及应变监测方法,结果表明:采用传统SHPB技术无法有效测量炸药类脆性材料的动态变形行为;通过采用波形整形技术控制加载波形,可以使试样在变形过程中较好地满足应力均匀性条件并改善应变率恒定性状况;通过采用在试样上直接贴片监测应变的方法,可以较准确的测得试样的应变。
3.
An improved method for obtaining dynamic stress equilibrium and nearly constant strain rate loading was proposed,containing pulse shaper design,nearly constant strain rate estimation,the optimum average strain rate determination and dynamic stress equilibrium analysis.
采用直径100 mm分离式霍普金森压杆(SHPB)试验装置,以碳纤维混凝土(CFRC)的SHPB试验为例,就试验过程中的波形整形技术展开研究,内容包括:波形整形器的设计、近似恒应变率的估算、最佳近似恒应变率的确定以及应力均匀性分析。
