黏接结构弱黏接缺陷的非线性超声评价
Nonlinear Ultrasonic Evaluation of Kissing Bond Defects in Bonded Structures
摘 要
利用ABAQUS有限元软件建立了非线性超声检测有限元模型，计算了弱黏接缺陷的尺寸对超声非线性系数的影响。计算结果表明：随着界面弱黏接缺陷尺寸的增大，超声检测信号基波幅值和二次谐波幅值逐渐减小，而超声非线性系数呈单调增大趋势。对5个含有不同弱黏接缺陷尺寸的AZ31镁铝合金黏接结构试样进行了非线性超声检测，研究发现试验结果与有限元计算结果相吻合，表明了非线性超声检测方法对黏接结构弱黏接缺陷检测的有效性。

Abstract
The finite element model of nonlinear ultrasonic testing was established by using ABAQUS finite element software. The influence of the size of kissing bond defects on the nonlinear coefficient of ultrasonic was calculated. The calculation results show that the amplitude of the fundamental wave and the amplitude of the second harmonic gradually decrease with the increase of the size of the interface kissing bond defects, while the ultrasonic nonlinear coefficient increases monotonously. The nonlinear ultrasonic testing of five AZ31 magnesium-aluminum alloy bonded structural specimens with different weak bond defects was carried out. The results show that the test results are consistent with the finite element calculation results, indicating the effectiveness of nonlinear ultrasonic testing method for kissing bond defect in bonded structure.
