Dear All,

I have been working with a simple solid element(IPE 300 Member) of 3 m length ( Pre-deformation was already given to the element using UPGEOM command considering my first mode shape from linear analysis).

I am trying to get the solid element's Graphical Representation of material behavior in Mechanical, like at what point the model reaches its plastic nature from elasto-plastic or from elastic point.

I tried to get the graph by scoping a relationship with Remote displacement and Reaction Force. But I get a graph which is linear till the end of load step. i.e. till 1 sec analysis setting.

Also i get a warning message saying that "large deformations are active which ay have invalidated some of your supports"

My boundary conditions for the model is, fixed support, displacement and a remote displacement.

Can anyone please help me with this.
