Online Webinar Training: Constraints | 28th May 2021 @ 11:30 - 12:00 CET

About the Webinar 

Most commonly, many of the FE Models which includes multiple parts are connected in some ways. The connection can either be a simple one like a fastened connection between two surfaces or may be a complicated one, where in order to have a desired level of accurate result, we may have to consider the relative kinematic effects in the FE Model. Therefore, an FE analyst must be well equipped to counter these challenges, by balancing the accuracy of the results and at same time ease the modelling efforts.

An overview of various constraints in Abaqus and its related issues will be presented in this Webinar. The aim is to help an FE analyst to counter such challenges in Abaqus modelling with high efficiency.

Use mesh-independent fasteners to simulate connection points in Abaqus

Posted by Christine Obbink-Huizer on Sep 9, 2019 10:30:38 AM

In short:

  • Mesh-independent fasteners couple layers of material to each other, simulating the effect of e.g. spot welds.
  • They don’t require the coupled region to be separated from other regions by a partition (mesh-independence), making them easy to define.
  • Instead their position is defined by attachment points, reference points or nodes.
  • It is possible to create patterns of attachments points, to easily define the location of multiple fasteners.
  • Fastener are defined from the interaction module, via “special”, “fasteners”, “create” or the “create fasteners” icon.
  • Rigid MPC fasteners are possible. The behavior of the fastener can also be defined via a connector section to allow more complex behavior.
