摘要

设计了能够真实反映Ⅲ型断裂的边缘环裂纹转转试验，讨论了胶黏剂种类和厚度对胶接结构失效模式的影响。结合峰值转矩和应变能释放率进一步揭示胶接结构的断裂特性。通过试验与仿真对比，推导出考虑厚度效应的内聚力模型参数表达式。研究表明，Araldite 2015胶的峰值转矩和应变能释放率随着胶黏剂厚度增加而增加，E-120HP胶和WD3705胶的峰值转矩和应变能释放率随着胶厚的增加呈现先增大后减小的规律。为合理评估胶黏剂种类和厚度对Ⅲ型断裂下胶接结构的失效机制的影响提供依据。

Abstract

Failure mode of bonded structure under different adhesive types and different adhesive thickness was discussed by designing the edge ring crack torsion test which can truly reflect mode III fracture toughness. And the fracture characteristies of bonded structure are revealed by combing the peak torque and strain energy release rate. Through the comparative analysis of experiment and simulation

parameter expression of cohesive zone model which considered the thickness effect is deduced by inversion method. The results show that the peak torque and strain energy release rate of Araldite 2015 increased with the increase of adhesive thickness. While the peak torque and strain energy release rate of E-120HP and WD3705 showed a concave trend with the increase of adhesive thickness. This study provides a basis for reasonably evaluating the effect of adhesive type and thickness on the failure mechanism of bonded structures under type III fracture.
