Keywords:Buckling, Contact Problem, FEM

In this paper, out-of-plane deformation pattern simulations of notched sheet in small gap were proposed. A method to extract buckling points on equilibrium paths, in which reaction force vector would change depending upon their contact status, and to show the possible existence of a bifurcation paths extending from the buckling points is developed.
