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.
