WebMethod 2: Nonlinear Buckling Static Analysis •Let’s re-visit the governing equations of static analysis. •In the event of buckling, the reaction force term drops nearly to zero and force balance is not achieved. •As a result, the structure is not longer in a static state so solving the problem as static analysis becomes difficult.
