Buckling Analysis

A buckling analysis is required where it is important to investigate the potential effects of buckling on the structure. These effects can be significant well before a structure actually buckles.

There are two approaches to buckling – eigenvalue buckling and nonlinear buckling. Eigenvalue buckling analysis looks at buckling load factors and the corresponding buckling mode shapes, for a structure with a particular load. Nonlinear buckling analysis looks at the response of the structure to a particular load as the load is increased and the effects of buckling begin to show. Nonlinear buckling cannot, in general, reveal higher modes.
