针对摩擦力效应产生的机理,本文设计了三种不同尺寸的试件进行SHPB实验,得到了摩擦力效应对实验的定量影响,在此基础上对混凝土的DIF进行了修正研究,为混凝土抗冲击工程设计提供了参考依据.
Aiming at the mechanism of friction effect, three kinds of specimens with different sizes were designed for SHPB experiment, and the quantitative effect of friction effect on the experiment was obtained. Based on this, the DIF of concrete was revised and studied, Engineering design provides a reference.
