Dispersion Curves of Rayleigh Waves and Lamb Waves

The dispersion curve program for Rayleigh and Lamb waves enables the plotting of dispersion curves based on experimental data and analysis of dispersion characteristics in various materials. The program typically implements numerical solutions to the wave equations, such as the Rayleigh-Lamb frequency equations, using root-finding algorithms like the bisection method or Newton-Raphson iteration. Through this program, we can better understand material physical properties and provide more accurate data support for applications. Additionally, the program facilitates the study of material acoustic properties, including density, elastic modulus, and Poisson's ratio. Key functions may include material parameter input validation, dispersion curve calculation modules, and visualization components for phase/group velocity plots. By conducting in-depth research on these characteristics, we can enhance our understanding of material performance and applications, thereby providing comprehensive information for engineering design and material selection.
