Generates dispersion curves for rods & tubes
4.0
Generates dispersion curves for rods & tubes .Finds the coupling of external fields to the propagating modes of the % waveguide. The excitation sources are stresses applied in the inner and % outer surfaces of the tube (specified by function PCEXTSTRESS) and % volumetric forces which act in the material of the tube (given in function % PCEXTVOLFOR). The coupling coefficients are evaluated in a frequency sweep % over the different modes considered, by integrating along the axis Z and % then the surface or the volume of the tube.

Dispersion curve calculation rod structure and tub
5.0
This program will rod structure and tube structure of frequency bulk curve solution integrated to together, just to change structure of both inside and outside radius size on can obtained above two species structure of frequency bulk curve, such as Dang take within RADIUS a=0, outside RADIUS b=c, is is rod structure of frequency bulk curve; Dang within RADIUS a=c, outside RADIUS b=d Shi, at obtained is both inside and outside RADIUS respectively for a,b of tube structure of frequency bulk curve, very convenient shortcut.

Lamb wave dispersion curves
4.0
Lamb wave dispersion curves in the plate-type structure with frequency dispersion and characteristics of Multimode, divided into symmetric modes and anti-symmetric modes, with a common analytical method for calculation and analysis of very complicated, this program through the MATLAB programming well calculated the Group velocity and phase velocity of lamb waves dispersion curves.
