Previous articles have discussed the application of statistics in tolerance analysis: how statistical addition works, how to incorporate the influence of different distributions, and combining worst-case with statistical contributions. The resulting picture is that... by Jaap Vink | 22 Apr 2021
Up to and including release 3.2.0 of HertzWin, all calculated results related to a static situation. The most important material stresses for a static situation are the maximum shear stress and the Von Mises equivalent stress. Most commonly used to determine whether a...

With the program HertzWin you can calculate Hertz point and line contacts. The influence of a tangential force can also be calculated. HertzWin has been available online for free since March 2009. No approximation but the exact solution In older releases of HertzWin... by Jaap Vink | 21 Apr 2020
In previous articles about tolerance analysis, I discussed the step-by-step plan and the way of adding up. Adding up tolerances can be a worst-case sum or a statistical sum. In ‘The distribution of tolerances’ I also discussed the types of distributions... by Jaap Vink | 28 Jan 2019
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... by Jaap Vink | 3 May 2017
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)...
