应力波传播规律研究中的一种快速分析方法

本文提出了一种能快速、简便、直观地分析了应力波传播状况的方法。该方法利用可视化计算并绘制流前图，而后将其与动光弹条纹图相比较，进而利用所推导的应力波迭加分析式判断出物体边界或其内部的应力波迭加效果。文中对圆盘中的几个典型区域进行了实例分析。

A PROMPT WAY TO ANALYSE STRESS-WAVE PROPAGATION

This paper presents a new method such that the stress-wave prpagation through a solid body may be analysed promptly, conveniently and apparently. In this method, the wave-front patterns may be calculated and be drawn by the use of the visual-technique and then be compared with the experimental fringe patterns from the dynamic photoelasticity. Furthmore, following the deduced theoretical equation, the effect of the stress-wave interacting on the boundary or acting inside of the specimen body may be investigated. Finally in the paper, several typical regions of a circle plate specimen being subject to stress-wave propagation, are analysed.
