How to define a part as rigid body?

Recommended Posts

Hi,

with Inspire 2016, you have to define rigid bodys as parts with a high e-modulus. With Inspire 2017, you can do this more easy with a rigid element.

Please have a look at the attached picture, showing deformation and stresses for two blocks under tension in different versions.

1. Conntected via RBE2 (Rigid Element)

2. A block with a material property with a very high e-modulus (200.000e12)

3. Another block but with usual steel for comparison

Hope this helps!

 

Kind Regards

Well,

you don't have to assign an RBE2 to a plate, just substitute the plate with the RBE2. Therefore choose the connector and connect the parts (in this case the edges) which are connected to the former plate. Then you can switch their type from "Flexible"->RBE3 to "Rigid"->RBE2:
