Hi guys,
I'm modelling a thin plate (4mm) under in-plane loads (axial loads) that has a high Elastic Modulus (E = 10^7 MPa) in order to get a plastic behavior (disregard the initial elastic deformation).
The load-displacement curve (axial load VS out of plane displacement) starts loose axial resistance while the lateral displacement increases, as expected, but at some point, the lateral displacement changes (invert) and the deformation shape bounced back.
Does anyone know how this behavior can be avoided (invert the lateral displacement)?
Thanks
