Compression only elements

Recommended Posts


I'm tring to model a semplified 2D pin element using RBE and CBAR with rotational dof release along the normal to plane.

Due to geometrical and load condition the RBE express a tension/compression on dipendent nodes.

my question is: si possible using an element (such as rbe) that is rigid in compression and not rigid (deactivated?) in traction?

Try PBUSD1D of type SPRING . You can specify different tables for spring stiffness in tension and/or compression. And specify very high stiffness for compression.
