对粘接界面在拉伸过程的变形破坏过程进行了观察,对获得的图像采用数字图像相关方法进行处理,获得了界面的位移场,进而分析其变形演化过程与细观破坏机理。结果表明:数字图像相关方法可以有效地分析粘接界面中细观破坏过程,界面的细观破坏经历损伤的累积及局部化过程,最终沿某一局部化带发生宏观破坏。 The process of deformation and failure of the bonding interface during the stretching process was observed. The obtained image was processed by the digital image correlation method, and the displacement field of the interface was obtained. Then the deformation evolution process and meso-failure mechanism were analyzed. The results show that the digital image correlation method can effectively analyze the meso - failure process in the bonding interface, the meso - damage in the interface undergoes the accumulation and localization of the damage, and finally the macro - damage occurs along a certain localization zone.
