Abstract

We present the study results of acoustic anisotropy and anisotropy of the Young’s and shear moduli, the Poisson’s ratio, and transverse deformation along with nonuniformity of anisotropy over the area of the studied thick carbon St3sp steel sheet performed with the electromagnetic–acoustic technique of emission and detection of elastic waves. The longitudinal and shear waves of various polarizations are used. The dependences of the velocity of the SH-waves and the Poisson’s ratio on the sheet thickness have been obtained. We have presented the angular indicatrices of the change in the velocity of the SH-wave as a function of the polarization direction and indicatrices of the Poisson’s ratio along with the calculated values of the Poisson’s ratio weighted average over the sheet plane.

摘要

我们展示了声学各向异性和杨氏模量和剪切模量的各向异性、泊松比和横向变形以及所研究的厚碳 St3sp 钢板区域的各向异性不均匀性的研究结果,这些研究结果是使用电磁声学技术进行的。检测弹性波。使用了各种极化的纵波和横波。已经获得了 SH 波的速度和泊松比对板材厚度的依赖性。我们已经提出了作为极化方向函数的 SH 波速度变化的角度指标和泊松比的指标,以及片材平面上泊松比加权平均值的计算值。
