采用动态光弹性、动态有限元分析和条纹照相等方法研究了由Homalite-100和聚碳酸酯板加工而成的改进型紧凑拉伸试样（M-CT）的动态断裂和止裂响应。与已发表的一些涉及钢M-CT试样的结果相反，在Homalite-100和聚碳酸酯M-CT试样的快速裂纹扩展过程中观察到大量的动态效应。动态止裂韧性K1 a相对恒定，分别约为Homalite-100和聚碳酸酯相应断裂韧性K1 c的80%和50%。
The dynamic fracture and crack-arrest responses of a modified compact-tension specimen (M-CT) machined from Homalite-100 and polycarbonate sheets were studied by dynamic photoelasticity, dynamic finite-element analysis and streaking photography. In contrast to some of the published results involving steel M-CT specimens, substantial dynamic effects were observed during rapid crack propagation in the Homalite-100 and polycarbonate M-CT specimens. The dynamic crack-arrest toughnesses.K1a, were relatively constant and were about 80 percent and 50 percent of the corresponding fracture toughness,K1c, of Homalite-100 and polycarbonate, respectively.
