Abstract

The paper presents the possibilities to estimate 304 steel plate’s plastic deformation using spectral analysis of the amplitude of difference and sum frequencies resulting from mixing of two Lamb waves with different frequencies. An electromagnetic acoustic transducer (EMAT) is used for the excitation of Lamb waves. The numerical modelling of the results of Lamb wave interference in a plate under tensile deformation is carried out; a comprehensive nonlinear factor is proposed and its sensitivity to the tensile deformation has been evaluated. Experimental verification of the modelling results is carried out. The experimental results show that this factor can be used to evaluate 304 steel plate’s tensile deformation quantitatively. This evaluation can eliminate the redundancy between difference frequency nonlinear parameter and sum frequency nonlinear parameter, as well as, improve the complementarity between the two parameters.

利用电磁超声λ波混合法评估 304 钢板的拉伸变形

摘要本文介绍了利用对两个不同频率的 Lamb 波混合产生的差频和和频振幅进行频谱分析来估算 304 钢板塑性变形的可能性。使用电磁声换能器（EMAT）来激发 Lamb 波。对板材在拉伸变形条件下的 Lamb 波干涉结果进行了数值建模；提出了一个综合非线性因子，并评估了其对拉伸变形的敏感性。对建模结果进行了实验验证。实验结果表明，该因子可用于定量评估 304 钢板的拉伸变形。该评估可以消除差频非线性参数与和频非线性参数之间的冗余，并提高两个参数之间的互补性。

期刊介绍： Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
