本文报告了用液压加载方法对模拟缺陷容器进行激光全息照相无损探伤试验的初步结果。分析对比数种缺陷形状所对应的畸变干涉条纹及形成规律,可作为容器探测中判断容器裂缝的特性和尺寸的依据。
This paper reports the preliminary results of laser holographic non-destructive testing of simulated defective containers by hydraulic loading. Analyzing and comparing the distortion fringes and the formation rules corresponding to several kinds of defect shapes can be used as the basis for judging the characteristics and the size of the container cracks in the container detection.
