GLARE层板低速冲击的实验与模拟
|
摘要
研究玻璃纤维增强铝合金层合板(glass fiber reinforced aluminum laminates,GLARE)在落锤低速冲击下的材料行为,建立ABAQUS有限元模型进行模拟并对其进行实验验证。针对纤维金属基体材料的特点,采用连续损伤模型(continuous damage model,CDM)分别给予落锤6.22 J、12.38 J和14.46 J的冲击能量,在ABAQUS中对模型设置相应的边界条件和载荷,得出落锤下落方向的速率-时间曲线和能量损耗曲线图。考虑金属层与复材层间黏结层的作用,采用凝聚层(cohesive)将金属层和复合材料层粘接。在仿真中观察层间的纤维和基体拉伸和压缩损伤状态及破坏情况,并与实验得出结果进行对比。结果显示:有限元仿真可以准确模拟落锤冲击之后GLARE板背面的裂纹和鼓包的实效情况以及基体和纤维的损伤情况,很好地预测复合材料内部的损伤情况。
The material behavior of glass fiber reinforced aluminum laminates(GLARE) under low-speed impact of a falling hammer was studied,and a finite element model of ABAQUS for simulation and experimental verification was built.According to the characteristics of fiber metal matrix materials,the continuous damage mechanics(CDM) model was adopted,and the impact energy values of the falling hammer were set as 6.22 J,12.38 J and 14.46 J respectively.The corresponding boundary conditions and loads of the model in ABAQUS were confirmed to obtain the velocity-time curve and energy loss curve of the falling direction of the falling hammer.The cohesive layer between metal layer and composite layer was taken into consideration,and the ‘Cohesive Layer ' in ABAQUS was adopted to bond metal layer and composite material layer.The tensile and compressive damage states of fibers and matrix in simulation were observed and compared with the experimental results.The results show that the finite element simulation can accurately simulate the crack and bulge effect on the back of GLARE laminates after the impact,as well as the damage situation of the matrix and fiber,so as to well predict the internal damage of the composite material.
