Hello Abaqus users, is it normal to get a different post-buckling path between Abaqus and MATLAB for beams?

The difference appears after the critical buckling load.

Well, this is very different software and we don't know the MATLAB code you are using. Is the setup (boundary conditions, loads, imperfections and so on) exactly the same ? Most likely element formulation and nonlinear solver differ a lot.
