MATLAB频散曲线绘制，相速度，群速度(MATLAB dispersion curve drawing, phase velocity, group velocity)

Lamb波的频散曲线是进行超声Lamb波无损检测的重要依据。本程序对Rayleigh2Lamb方程进行了分析，给出了无限大板中Lamb波频散曲线的数值计算方法，通过Matlab软件对求解过程进行编程，绘制出Lamb波在铝板中传播的相速度和群速度曲线，并通过试验进行了验证对推广应用Lamb波进行无损检测具有实际意义。(The dispersion curve of Lamb wave is an important basis for non-destructive testing of ultr

Lame波的频散曲线，包括相速度和群速度。(The dispersion curve of Lame wave includes phase velocity and group velocity.)
