【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。更多还原

【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更多还原
