You can't "accurately" simulate it using Inventor alone. You would need Nastran or other non-linear capable solvers.. Inventor FEA does linear materials only.&nbsp;</P> <P>Example of faking it..</P> <P><A href="https://www.youtube.com/watch?v=nq4_kffB_7E" target="_blank">https://www.youtube.com/watch?v=nq4_kffB_7E</A></P> <P>&nbsp;</P> Tue, 08 Nov 2022 14:48:01 GMT https://forums.autodesk.com/t5/inventor-forum/simulate-the-extension-of-rubber/m-p/11538650#M62355 mcgyvr 2022-11-08T14:48:01Z
