Obtain cross-section forces

[AkbarAkbar]

Hello everyone,

I am trying to obtain the history of cross-section forces (3 forces and 3 bending moments) from a 3D-Shell

Anyone can give me some suggestion? What should I do to take out cross section forces?

Thanks in advance.

Hi everyone,

I am running post-buckling analysis to investigate the stability response of an isolated column. There are two "step": Static,General(Step 1) with axial force on top and Static, RIKS (Step 2) with horizontal displacement on top of column. Once the column starts to buckle in RIKS analysis, Time/LPF Inc. is changing to negative value (Arc Length is almost constant) and horizontal displacement is reversed!!! As I need to look at the column response in post-buckling range, top displacement should reach to the target displacement that I specified but this does not happen?

I do not really understand the issue regarding the RIKS analysis.

Anyone can give me some suggestion?

Thanks in advance
