摘要
讨论了胶层中的粘弹性对单搭接胶接接头拉伸剪切强度和应变的影响,认为胶层一般具有的粘弹性与应力集中程度间有较为密切的关系试验结果表明:在胶接接头经历拉伸剪切试验时,加载速率对接头强度和应变有显著的影响。
Concerns the analysis of the shear strength and the strain of viscoelastic adhesive single lap joint when tension load time rate to fracture varies The authors believe that there is a close relation between the viscoelasticity of the adhesive layer and the stress concentration level of single lap joint It is shown that in case of tention loading test of single lap joint, shear strength and strain depend on the time rate of loading and the viscoelasticity of adhesive layer plays a important roll in it
