9414740 Kumosa This research will investigate mixed mode fracture and failure mechanisms in polymer matrix composites and adhesively bonded polymer composite systems subjected to biaxial loading conditions. This research will significantly contribute to the understanding of high temperature mixed mode micro- and macro-fracture mechanisms in unidirectional polymer matrix composites caused by biaxial loading and provide new insights into the mixed mode failure of adhesively bonded polymer composite systems tested under static and cyclic loading conditions under biaxial loading. A possible practical significance of the proposed work is that the biaxial test method being proposed can become a standard test for mixed mode fracture analysis of many advanced composite systems over a wide temperature range. ***

9414740 Kumosa本研究将研究双轴载荷条件下聚合物基复合材料和粘结聚合物复合材料系统的混合模式断裂和失效机制。 这项研究将显着有助于理解高温混合模式的微观和宏观断裂机制在单向聚合物基复合材料所造成的双向载荷和提供新的见解混合模式下的破坏的粘接聚合物复合材料系统在静态和循环加载条件下双向载荷下进行测试。 所提出的工作的一个可能的实际意义是，双轴测试方法被提出可以成为一个标准的测试混合模式断裂分析的许多先进的复合材料系统在一个很宽的温度范围。 ***
