Stress wave propagating in elastic structures under impact or explosive loading is a very difficult problem analytically. But the problem could be analysed by dynamic photoelasticity.
爆破与高速冲击载荷产生的应力波在弹性结构物中的传播，在理论分析上极为困难，但这类问题可以用动态光弹性法进行分析。
The tests prove that saturated soils are a kind of strain hardened media and stress wave will maintain shock wave characteristic invariant during shock wave dynamic loading.
试验证明，饱和土属于应变硬化介质，在激波动力加载条件下，土中应力波将保持其激波特征不变。
To study the dynamic response properties of brittle rock under strong impact loading, the stress wave curves were measured using the planar impact technique.
