| 摘 要： | 文中采用组合圆盘粘结试件,对胶层端部引入圆弧面构造并对钢质基体进行倒角处理,能够在胶层中形成均匀系数高达0.97以上的剪应力分布,并将粘结面上的正拉应力控制在很低的水平。利用INSTRON单轴伺服试验机高精度的内置位移测试系统,将系统变形从总变形中予以剔除,从而获得胶层竖向变形,并最终换算成胶层的剪切变形和剪应变。采用样品胶体进行的组合圆盘剪切试验表明,粘结件以胶层剪切破坏为特征,随后胶体与金属基体脱层,因此组合圆盘试验方法能够反映材料受剪性能,强度测试值可作为材料强度条件使用,受剪应力应变本构关系可在粘结构件承载力计算分析中应用。组合圆盘试验方法较为简单,适合在具有位移控制功能的伺服试验机系统的实验室采用。

| Abstract: | This paper uses the combined bonding disc specimen,with a round end surfaces at both ends of the longitudinal adhesive joint and chamfered steel substrates hither,forms a shear stress distribution of uniform coefficient more than 0.97 and controls the normal tension stress along the bonding surfaces to a very low level.By means of the built-in high accuracy displacement measuring system of uniaxial INSTRON servo equipment,it eliminates the measuring system deformation from the measured total deformation,and... |
