Hello Dear All.
I am simulating specimen SC02 of the article :

since I am fresh in abaqus I am unable to adjusted step module. for both analysis:
(The first type is Eigenvalue buckling analysis which is used to estimates the first buckling mode. The second type is to perform inelastic geometrical nonlinear analysis in which the first buckling mode obtained from the buckling analysis is factored by a magnitude of Lu/1000, where Lu is the length between points of effective bracing, and is used as initial imperfection of the structure members to initiate the local buckling in the component plates. In order to prevent local yielding around the loading point, the concentrated load is simulated by a uniform pressure distributed above an elastic rigid solid element. The arc length method (Riks) with the aid of full Newton-Raphson iteration method is used to trace loading path till failure point is reached).
Please guide me to make the correct settings. (step, field output & history output)
sincere thanks.
Ali Mirzaee Please check the attached Abaqus input file, in which a buckling eigenvalue analysis is performed, followed by a geometrically nonlinear static RIks analysis, for the evaluation of the postbuckling response of a beam. This input file can be easily modified to add the geometry, materials, sections, loads and boundary conditions of the specimen that you are analyzing.

Dear Ali,
In Riks analysis, one of the important factors is imperfection that must be considered. Also in this method, a force is applied and the displacement force diagram is drawn. Try the following settings on your model.
