同时使用2台CCD相机作为数据采集手段,利用数字散斑相关方法对实验中采集的图像数据进行分析,对单轴压缩条件下混凝土试件变形演化进行实验研究;将分析数据导入MATLAB双向显示程序中,实现了单轴压缩实验中混凝土试件变形破坏变形场的双向显示,分析了混凝土试件受压破坏全过程中双向显示下的变形场演化过程.
At the same time, two CCD cameras were used as the data acquisition method. The digital speckle correlation method was used to analyze the image data collected in the experiment. The deformation and evolution of concrete specimens under uniaxial compression were experimentally studied. The analysis data were imported into the MATLAB bidirectional display program , The two-way display of deformation and deformation field of concrete specimens in uniaxial compression was achieved. The evolution of deformation field in two-way display of concrete specimen under compression and failure was analyzed.
