Abstract

In this study, we applied the reverse time migration (RTM) method to ultrasonic defect imaging in anisotropic materials. RTM offered that the defect shape could be uniquely determined by calculating a cross correlation of the incident and the reverse propagated waves from the array transducer. 2D simulations demonstrated that defect imaging by the RTM method requires an accurate numerical setup. We validated our technique using measured scattered waves from a slit in unidirectional solidified 316L stainless steel. By using the elastic constants determined from the ultrasonic wavefield data, the slit shape was correctly reconstructed. This provides a proof of principle that the RTM method is effective in nondestructive imaging of composite structures containing anisotropic materials.

逆时偏移法在各向异性材料超声无损成像中的应用
在本研究中,我们将逆时偏移(RTM)方法应用于各向异性材料的超声缺陷成像。RTM提供了通过计算入射波和阵列换能器反向传播波的相互关系可以唯一确定缺陷形状的方法。二维仿真结果表明,采用RTM方法进行缺陷成像需要精确的数值设置。我们通过测量单向凝固316L不锈钢狭缝的散射波来验证我们的技术。利用超声波场数据确定的弹性常数,正确地重建了狭缝形状。这为RTM方法在含各向异性材料的复合材料结构无损成像中的有效性提供了原理证明。
