Hi all,
The beam is subjected to an axial load and end moments and I’m trying to find the critical end moment loads (Mcr) that cause buckling.
I have a thin-walled hollow 2ply-composite beam (modelled with shell elements in Abaqus) that is simply supported (LHS is pinned, RHS is a roller support). The beam is subjected to an axial load and end moments.
When no end moments are applied I am able to find the critical buckling load (Pcr, axial load), but as soon as soon as I start incorporating end moments I am running into issues.
Does any one have any experience with applying end moments to a thin walled beam for buckling analysis?
