Buckling stress calculation
WebThe buckling loads are calculated relative to the base state of the structure. If the eigenvalue buckling procedure is the first step in an analysis, the initial conditions form the base state; otherwise, the base state is the current state of the model at the end of the last general analysis step (see General and perturbation procedures ). WebThe first case is a trivial case, it corresponds to no deflection, and therefore no buckling – it describes the case when the axially applied load simply compresses the beam in the x …
