3439 積層材料における界面き裂のモードII破壊に関する研究(G03-7 複合材料,G03 材料力学)
詳細
The impact phenomena have probrems of the stress wave propagation and the material property. Therefore, the impact phenomena are complex. The flow of power on the interface in the composite materials and the laminated materials is complicated and there are a lot of related factors of the complexity of the contact condition. From this cause, stress analysis and the strength evaluation are difficult. In this study, we made the laminated materials bonding different polymeric materials, and analyzed the dynamic fracture behavior of the interfacial crack with a high-speed video camera. The displacement of the interfacial precrack tip proximity was measured by using the digital image correlation method for the analysis.
