Announcing free version of Kalker's rolling contact model

Submitted by Edwin Vollebregt on

Dear all,

Herewith I would like to announce that we have decided to make our CONTACT software publicly available. You can obtain a free copy at the web-site www.kalkersoftware.org. We hope that the software is beneficial to you. We further hope that you give us helpful feedback in return.

Hi, i am working with ansys multiphysics, i want to apply a hydrostatic pressure, gradient of pressure, as a load on a cylindrical structure. i found that commande on its help "Main Menu> Preprocessor> Loads> Define Loads> Settings> For Surface Ld> Gradient" but i dont know how to use it. is there any recommandation? thx

2D dynamic analysis

Submitted by sherazi21st on

In the figure I showed a mechanism, I want to make an analysis for that. consider the circles in the figure as cylenders which can be seen in the top view. these circles are regular cylenderical parts. I made the fig in paint thats why circle don't seem to be regular. I want to analyze the angle that at given angle, whether the rolling flow of these cylenders will be blocked or not. Please tell me some software to analyze in 2d Prefferably or 3d. Please help me. I'm in intense need.

A new Method for Detection of Degradation in Die-Attach Materials by In-Situ-Health Monitoring of Thermal Properties

Submitted by mazloum on

The application of electronic products is established in many fields of everyday life, for example in automotive industry, medical or communication technology. This leads to the necessity of investigation of safety and reliability of such components. During lifetime testing of the electronic component different loads and mechanisms can lead to degradation and failure. For die attach materials these failures can be cohesive or adhesive in their nature.
