爆炸过程中有关应力波传播问题探讨

摘要

针对爆炸过程中出现的3种常见应力波，对其传播速度和应力波幅值进行了讨论，指出应力波的传播速度及其引起的质点振动幅值均与材料的泊松比密切相关。对于应力波传播试验中出现的纵波、横波及瑞利表面波这3种常见应力波，从数值模拟的角度进行了再现。%In this paper three kinds of stress waves are studied mainly on two aspects; propagation velocity and amplification, it has been given that propagation and amplification relate to poission ratio of material.The three kinds of stress waves presented in stress wave propagation are also computer simulated, which displays some phenomena in stress propagation process.
