摘要

胶焊是将点焊技术与胶接技术结合使用的先进连接技术。由于众多优点,该技术越来越受到重视和应用,而其相关研究特别是对其长时蠕变应力的了解比较缺乏。本文利用三维粘弹塑性有限元法,对胶焊连接接头的时间相关应力再分布进行分析,并讨论了相关接头的设计和材料选择的改进方向。

Abstract

Weldbonding is a new joining technique that combines the spot-welding with the adhesive-bonding method. It was adopted more and more in recent years because of its many advantages However, the researches on this new technology are few especially on the long-term stress and strength of the weldbonded structures. A three-dimensional viscoplastic finite element model of single-lap weldbonded joint was developed in this paper to investigate its stress redistribution Some advice on joint design and material choice were discussed.
