摘要(Abstract):

利用全息动光弹研究了非均质层状模型在有无弱面条件下线型载荷应力波的传播特性,对两层介质中和上、下界面处的应力场变化进行了分析讨论,并得出相应结论.
With the aid of dynamic holographic photo-elasticity, characteristics of the stress wave propagation are studied in anisotropic layered media by a linear charge. In the paper,stress changing at the section layered (up and down sauface) and in two kinds of the media areanalyzed. Some conclusions are given.
