Lamb Wave Dispersion Curve

Generate Lamb wave dispersion curves of an isotropic material

A simple program that calculates lamb wave dispersion curves of a simple isotropic material like aluminum.

Input:

E = Young's Modulus

v = Poisson's Ratio

D = Density

d = Material Thickness

mode = Number of modes required

len = Minimum interval

maxf = Maximum Frequency.

cps and cpa are phase velocities of symmetric and anti-symmetric modes respectively, similarly for cga and cgs

For Example

[cps,cpa,cgs,cga] = LambDispersion(7.24e+10,0.33,0.001,2780,8,10,20000)
