Analysis of Transmission Coefficient of Blasting Stress Wave Entering Structural Face of Certain Depth
【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。
【Abstract】 According to basic theory of wave, a theoretical equation is derived for calculating transmission coefficent 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 similiar model. It is concluded that the stress transmission rate varies with stress wave′s incident angle.
