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.

If its worthy, you can also take a look at http://www.tribonet.org/hertz-pressure-calculator/ - online calculator of Hertz contact. There is also contact simulator: http://www.tribonet.org/cmdownloads/tribology-simulator/ - for stress and subsurface stress calculation of non-elliptically shaped geometry.

Updates

1.6

improve errors and increase calculation speed.

1.5

updated units and dimension. revised bugs.

1.4

I updated it with improvement of Hertz theory (K4 value).

1.3

I fixed Kalker's theory part and added compare function to see how different two theories are.

1.2

I uploaded m and fig files together

1.1
