Breakthrough in accurate load mapping for bulk materials applications: DEM – FEA Coupling with ROCKY 3.0 and ANSYS (Part 1)

Today we present a new and easy way to transfer loads from DEM simulations (ROCKY version 3.0 released September 2014) to ANSYS using External Data coupling in ANSYS Workbench. Discrete Element Method and ROCKY The Discrete Element Method (DEM) is a computational technique originally developed in the 1970s that has gained great popularity in recent…

What is Fatigue?

Fatigue is failure under repeated or otherwise varying load which never reaches a level sufficient to cause failure in a single application. Component seems to lose strength after multiple load applications, appears to get tired, hence the name “fatigue”.     Failure caused by fatigue can be minor or catastrophic. The consequences of failure are…
