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.
