摘要
对不同性质缺陷回波中纵/横波分量的CIVA软件的仿真试验,以及不同性质模拟缺陷的检测试验。结果表明:横波入射时,检测出的面积性和体积性缺陷回波信号中,纵波和横波的分量幅度的相对量有差异,同时可以通过相对量的大小,判定缺陷是面积性缺陷还是体积性缺陷。
The simulation result of CIVA software and the test result of analog defects has shown that when the defect is hit by shear wave,the echo has both longitudinal wave and shear wave.According to the relative amounts of longitudinal and shear wave,defect types(planar defect or volume defect)can be determined.
