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... 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)... by Jaap Vink | 27 Jan 2012
The flexure hinge is a tried and tested construction element in precision engineering systems. It is created by drilling or spark erosion of two adjacent holes. The positive properties of flexure hinges (free of play and friction) are partly undone by the limited... by Jaap Vink | 27 Jan 2012
The HertzWin program developed by Vink System Analysis & Design is used by many. Sometimes these users have questions in relation to the accuracy of the HertzWin results. Some of them are discussed here. Does the program contain computational errors (bugs)? In...
