摘　　要：用有限元分析的数值模拟方法(A N SY S)研究剪切散斑无损检测,已经受到了人们的极大关注。以剪切散斑无损检测为背景,以有无缺陷试件为模型,对模型进行有限元总体分析,运用计算机数值模拟出在载荷作用下含缺陷试件覆盖层的形变状态。结果表明,当缺陷变化时,对最大离面位移差均有不同程度的影响,未来可以将此方法应用于无损检测中,从而定量检测出缺陷的位置。Taking use of ANSYS to study speckle-shearing nondestructive testing has attached great concern of people. Taking speckle-shearing NDT as the background, and non-defective specimen a model,this paper made generalanalysis of the model finite element, stimulated deformation state of defective specimen coating under the effect of loading. The results showed that the changes of defect has affect on maximum displacement out-of-plane difference in varying degrees, and this method can be applied to NDT in the future so as to quantitatively detect defect location.
