This GUI program calculates some of specific data during the contact between wheel and rail.

File Information

This GUI program might be able to calculate the contact size and contact pressure on the contact patch by Hertz theory. The program also calculates normal force versus creepage comparing both Johnson and Vermeulen theory and Kalker's theory. It might be a good tool to visualize contact.

I uploaded fig file to work m file better.

21 Sep 2011 1.2

I uploaded m and fig files together
