摘要
从加速老化试验方法、胶接结构老化规律研究以及界面脱黏数值模拟3个方面回顾了过去对于胶接结构老化脱黏行为的相关研究。重点介绍了模拟老化的各类人工加速试验方法,常用的针对老化加速试验的寿命评估模型,以及胶接结构老化后材料性能退化的规律研究。还介绍了采用虚拟裂纹闭合技术(VCCT)、内聚力模型(CZM)以及渐近损伤方法(PDM)模拟结构脱黏行为的研究现状。最后,对胶接结构老化脱黏行为的研究进行了总结与展望。
The work reviewed the research on the aging and debonding behavior of adhesive structures from three aspects:accelerated aging test methods,aging law of adhesive structures and numerical simulation of interfacial debonding.Various arti-ficial accelerated test methods for simulating aging,commonly used life assessment models for accelerated aging tests,and the degradation law of material performance after aging of adhesive structures were introduced.The research status of using the Virtual Crack Closure Technique(VCCT),Cohesive Zone Model(CZM)and Progressive Damage Method(PDM)to simulate the debonding behavior of structures was also introduced.Finally,the research on the aging debonding behavior of adhesive structures was summarized and prospected.
