A Dynamic Photoelastic Analysis for the Effect of Different Cushion Layers on Stress Wave Propagation in Structure
用动光弹性法研究材料引入的分配层对应力波传播的影响

The effect of different cushion layers on the stress were propagation in structure were investigated by dynamic photoelastic method.The propagation and interaction of stress waves in structure were compared under shock load, and stress vs time curves at appointed points were obtained. The experimental results can provide reference for further research on structural spllation and for improvement of protective construction.
