Is it possible to execute a non linear analysis with small displacements by OptiStruct?
Hi @stefano.carrino
Yes, please use NLSTAT analysis type (non linear quasi-static analysis)
Thank you Prakash,
but I need to execute a transient analysis in order to simulate a packet wave propagating through a delamination (for this reason the analysis is non linear because I´m using a contact with possibility of separation).
Can you try with RADIOSS instead of OptiStruct?
There is a tutorial for RADIOSS about this analysis?
You can either do a non-linear transient which uses Large displacement in OptiStruct. Please search for non-linear transient in the forum to ger related posts. But, delamination effects can't be captured.
You can also perform an impact kind of analysis using RADIOSS. Unfortunately, we don't have a tutorial for the same.
