文章基于光弹性原理,采用枪击垂直实验获取应力波在不同界面结构中的等差条纹图,通过条纹图的对比分析,研究了结构在完整、部份截断、完全截断三种情况下应力波的传播规律。研究结果表明结构在部份截断情况下对应力波的传播起到了一定阻隔作用,但效果不明显;而结构处于完全截断时,应力波已经被完全阻隔。 Based on the principle of photoelasticity, the vertical strikes of gunship were used to obtain the contour lines of stress wave in different interface structures. By comparing the fringe patterns, the stress wave of the stress wave in the complete, partial truncation and complete truncation was studied. Propagate the law. The results show that the structure has a certain barrier effect on the propagation of stress waves under partial truncation, but the effect is not obvious. When the structure is completely truncated, the stress wave has been completely obstructed.
