Dear,

How are the rotationally restrained edges modeled? The spring constante is 100 N.m/m

By applying a Remote Displacement boundary condition,  I obtained the same buckling load as that obtained for a plate simply supported on four sides.

What are the boundary conditions for the side that has elastic constraints? I considered null displacement in y, restricted rotation in x and remote displacement (rotation). For rotation, I considered a unitary moment applied to the longitudinals. This way, the applied rotation is rot: 1/100 rad = 0.5729°. It is worth mentioning that M=k*rot (k=100 N.m/m).

See the figures, please.

Thanks

Perhaps you could scope a torsional spring to the edge using deformable behavior.
