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)
