用动光弹实验研究爆破机理的方法探讨

Blasting Mechanism Analyzed by Dynamic Photoelastic Experiment

动光弹实验是采用光学灵敏性材料制成与实物相似的模型,在动载荷作用下,用圆偏振光照射,在底板上直接记录模型中应力等差线的一种光学测量方法,它可以真实地反映出爆破过程的信息与规律。在介绍动光弹基本原理基础上对目前国内动光弹技术的应用现状作了分析。

The optics sensitivity material is adopted to make a model similar to material object by dynamic photoelastic experiment, it can reflect information and law of blasting process. The text dynamic photoelastic experiment and its basic principle are introduced.
