| 摘 要： | 对6种不同的复合材料板与钢板的连接接头,即单盖板胶接、螺接、混接,以及双盖板胶接、螺接、混接的连接接头进行了静力拉伸试验与数值研究。静力试验获得了接头的失效载荷、载荷-位移曲线以及失效模式,通过对比发现接头的承载能力与接头形式有很大关系。采用有限元方法获取了胶接接头中胶层应力分布,并研究了接头各设计参数如搭接长度、胶层厚度等对接头强度的影响规律。

| Abstract: | Six different types of composite-to-steel joints,namely single-strap adhesively bonded joint(SAJ),double-strap adhesively bonded joint(DAJ),single-strap bolted joint(SBJ),double-strap bolted joint(DBJ),single-strap hybrid joint(SHJ),double-strap hybrid joint(DHJ),respectively,were experimentally and numerically investigated under tensile loading.The failure loads,load-deflection curves and failure modes were then obtained and compared with each other.Test results show that the ultimate load or joint load-ca... |
