This review paper provides an exploration of various facets of creep behaviour in adhesives and adhesive joints, encompassing experimental procedures, prediction models, influential parameters and strategies to enhance resistance. The discussion extends to the interplay between fatigue and creep, emphasising recent advances over the last two decades. While avoiding redundancy with prior work on temperature and moisture degradation, the paper articulates connections between topics for a better understanding. A critical examination of load levels reveals that small variations significantly impact the creep life of adhesive joints, particularly prominent with epoxy adhesives. The adhesive type, joint geometry and substrate material are scrutinised, revealing distinct impacts on creep behaviour. The study underscores the critical role of adhesive thickness and overlap length, emphasising their relevance in determining the time to failure in bonded joints under creep conditions. Notably, the substrate material’s role is highlighted. As the review delves into unexplored dimensions, it calls for further research to bridge existing gaps and refine our understanding of tertiary creep and time until failure.

胶接接头的蠕变行为:全面综述

这篇综述论文对粘合剂和粘合接头蠕变行为的各个方面进行了探索,包括实验程序、预测模型、影响参数和增强抵抗力的策略。讨论延伸到疲劳和蠕变之间的相互作用,强调了过去二十年的最新进展。在避免与先前有关温度和湿度降解的工作重复的同时,本文阐明了主题之间的联系,以便更好地理解。对负载水平的严格检查表明,微小的变化会显着影响粘合接头的蠕变寿命,尤其是环氧粘合剂。对粘合剂类型、接头几何形状和基材材料进行了仔细检查,揭示了对蠕变行为的明显影响。该研究强调了粘合剂厚度和重叠长度的关键作用,强调了它们在确定蠕变条件下粘合接头失效时间方面的相关性。值得注意的是,基材材料的作用被强调。随着审查深入到未探索的维度,它需要进一步的研究来弥合现有差距并完善我们对三次蠕变和失效前时间的理解。
