Investigation of Lamb Wave Attenuation

In this paper attenuation coefficients were evaluated for steel 12Kh18N10T and steel 20. The results were compared with those obtained from finite element modelling (FEM) and analytical evaluation. Lamb wave attenuation coefficients of antisymmetric mode of zeroth order were evaluated from the FEM model calculations. The results derived from FEM simulations (attenuation coefficients of 6.940 dB/m/MHz and 8.686 dB/m/MHz for steel grades 20 and 12Kh18N10T, respectively), were validated with experimental data.

Abstract

In this paper attenuation coefficients were evaluated for steel 12Kh18N10T and steel 20. The results were compared with those obtained from finite element modelling (FEM) and analytical evaluation. Lamb wave attenuation coefficients of antisymmetric mode of zeroth order were evaluated from the FEM model calculations. The results derived from FEM simulations (attenuation coefficients of 6.940 dB/m/MHz and 8.686 dB/m/MHz for steel grades 20 and 12Kh18N10T, respectively), were validated with experimental data.
