This paper experimentally analyses the delamination behaviour of a composite material under mode III fracture as a function of the loading mode applied during the fatigue tests was carried out in two different ways. First, the test specimens were loaded cyclically in a single direction of delamination until reaching a certain fracture energy and subsequently returning to the starting point. Second, cyclic loading was applied both in one direction of delamination and in the opposite direction until reaching the same fracture energies, though in two opposite directions.

环氧/单向碳纤维复合材料中III型断裂的对称和不对称动态表征

本文通过两种不同的方式，对III型断裂下复合材料的层离行为进行了实验分析，作为疲劳测试过程中施加的加载模式的函数。首先，将试样在单个分层方向上循环加载，直到达到一定的断裂能，然后返回到起点。第二，虽然沿两个相反的方向，但在一个分层方向和相反的方向上都施加了循环载荷，直到达到相同的断裂能为止。
