A new version of the software for calculation of hertzian contact stress is available.

The software calculates hertzian contact stress and the subsurface stressen of the general contact of two elliptical bodies according to the hertzian theorie. Conditions are therefore small deformations in regard to the radii of curvature and pure elastic deformations. For example the contact pressure in contacts of rolling elements with races of a rolling bearing can be calculated. It has to be considered in this case that the radius of curvature for concave geometry has to be entered as negative number.

An example report of the calculation is available and you find the download of the software here. The software is available in english and german language. In addition there is an online version.
