本文提出了一种新的胶接接头三维有限元分析模型。该模型考虑了几何和材料的非线性，并使用固体砖元素以及专门开发的界面元素。界面单元允许计算被粘物-胶粘剂界面处的应力。应用该模型的单搭接接头。线弹性分析的结果突出了界面处应力和应力集中的三维性质。还讨论了材料非线性对接头性能的影响。(C)2002爱思唯尔科技有限公司版权所有。
This paper presents a new model for three-dimensional finite element analysis of adhesive joints. The model considers geometric and material nonlinearities and uses solid brick elements as well as specially developed interface elements. The interface elements allow the calculation of stresses at the adherend-adhesive interfaces. The application of the model to a single-lap joint is presented. The results of a linear elastic analysis highlight the three-dimensional nature of the stresses and stress concentrations at interfaces. The influence of material nonlinearities on the behavior of the joint is also discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.
