摘要
从波的基本理论出发 ,推导了爆炸应力波入射一定厚度结构面时透射系数的理论计算公式。通过对相似模型超动态应变的测试验证了所得理论公式的正确性 ,并获得了透射率随入射角的变化规律。
According to basic theory of wave, a theoretical equation is derived for calculating transmission coefficient of blasting wave entering a structural face of a certain depth, and proved to be correct and reliable through ultra-dynamic strain tests of a similar model. It is concluded that the stress transmission rate varies with stress wave's incident angle.
