摘要
通过使用数字散斑技术,研究不同强度试件下剪切破坏过程的演变,对剪切试验过程中的散斑图像进行采集和处理,根据得到的试件应变场,分析试件的变形破坏演化过程以及试件表面应变场的变化规律,最终得出了一些有意义的结论。
Through adopting digital speckle processing technology,the paper studies the evolution of shearing destroying process of the testing specimen with different strength,and carries out speckle image acquisition and processing in shearing experience.According to the obtained testing specimen stress-strain field,it analyzes its deformation destroying and evolution process and the changing law of the testing specimen surface stress-strain field as well,and finally draws some meaningful conclusions.
