Linear Static Analysis: To calculate the material and geometric stiffness of the structure

Eigenvalue Analysis: To generate the modal shapes

The results from the static analysis and eigenvalue analysis together give the resultant buckling shapes of the structure.

Buckling failure in structures occurs due to the geometric shape of the structure.

Typically, this failure occurs at a stress value lower than that predicted using static analysis. Buckling analysis is used to predict failure in long, slender structures. It is common to analyze buckling behavior in large steel structures that are commonly used in marine & offshore, mining and construction industries.
