Up to and including release 3.2.0 of HertzWin, all calculated results related to a static situation. The most important material stresses are then the maximum shear stress and the Von Mises equivalent stress. Most commonly used to determine whether a material is...

With the program HertzWin you can calculate Hertz point and line contacts. The influence of a tangential load can also be calculated. HertzWin has been available online for free since March 2009. In older releases of HertzWin (prior to release 3.1.2) a general...

In previous articles about tolerance analysis, I discussed the step-by-step plan and the way of adding up. The latter can be a worst-case sum or a statistical sum. In ‘The distribution of tolerances’ I also discussed the types of distributions that may...

Occasionally, contact stresses play a role in a mechanical design. Herzian stress equations are needed to calculate indentation and to check if the yield stress isn’t exceeded. Because programming is a hobby of mine, it seemed like a good idea to make a Hertzian...

Occasionally, I get the question why the content of the help function of one of the software applications from the toolkit isn’t visible. It only shows “Navigation to the webpage was canceled”. An other issue is that with high resolution (High DPI)...

In a previous article the statistical tolerance stack-up analysis is discussed. It is usually profitable to do a statistical tolerance stack-up analysis instead of a worst-case analysis. A worst-case analysis often leads to low tolerance specifications and therefore...
