    摘要
  • 摘要: 采用广义Maxwell（麦克斯韦尔）粘弹性本构模型表征胶黏剂的时间相关力学特性，采用Yeoh本构模型描述橡胶材料的超弹性，建立了钢-橡胶双搭接胶结接头的有限元计算模型.在此基础上分析了加载时间对接头粘接界面剪切应力的影响.计算结果表明，剪切应力绝对值随着加载时间的增长而减小.此外，分析了胶层厚度对接头粘接界面剪切应力的影响，随着胶层厚度的增加，剪切应力绝对值呈现明显的增大趋势.
    Abstract: The finite element model of steel-rubber double lap bonding joint was created. The generalized Maxwell viscoelastic constitutive model was employed to model the time-dependent mechanical properties of adhesive. The Yeoh constitutive model was applied to describe the super elasticity of rubber. The influence of loading time on the shear stress of adhesive layer was analyzed. Computed results clearly show that the absolute value of shear stress decreases with the increase of loading time. In addition, the influence of adhesive thickness on the shear stress of adhesive layer is analyzed as well. With the increase of adhesive thickness, the absolute value of shear stress firstly increases obviously.
