Plate Buckling

A 1cm thick steel plate with 1.200 x 2.400 m dimensions has articulated supports at its edges and is subjected to a compressive force in the direction of its long dimension.
A small point load at node 202 is applied as initial imperfection. Notice that this imperfection has little to do with the resultant buckling shape. It should be only asymmetric.You will find the input data file viaTEDDY > help > examples... > ase > english > ase12_buckling_slab.datThis example is documented in detail at the ASE manual - chapter 5.12Level of difficulty: advanced
