对称和非对称粘合单盖板节点的变形和应力分析

采用粘合节点连接各种结构构件日益增多。只有充分了解粘合节点的性能,才能保证这种节点的功效、安全和可靠性。有些节点的构造,如单、双搭接接头受到了重视,但单盖板的构造并没有得到重视,部分原因是早期的研究显示这种节点效率低。本文的目的之一是论证只要经过合理设计,盖板节点与搭接接头同样有效。这项工作通过详细分析粘合剂中峰值应力的参数影响来完成。另一个目标是提出一个简单的方程,能够使盖板节点的设计便利及有效。为此,对解析表达式进行了简化并给出精确的结果,并对影响边缘力的参数有了进一步的理解。

Analysis of Deformations and Stresses in Balanced and Unbalanced Adhesively Bonded Single-Strap Joints

Adhesively bonded joints are increasingly being used in joining various structural components. Adequate understanding of the behaviour of adhesively bonded joints is necessary to ensure efficiency, safety and reliability of such joints. While several joint configurations, such as the single-and double-lap joints have received considerable consideration, the single-strap joint configuration has received little attention, partly because earlier studies have shown it to be the least efficient. One of the objec...
