Buckling Theory

Buckling theory describes how and when a structural element, like a beam or column, suddenly bends or collapses under certain compressive forces. When subjected to increasing pressure, an element initially deforms slightly but remains stable. However, beyond a critical load, it rapidly shifts into a deformed shape, risking failure. The theory helps predict this critical load based on the material’s strength, shape, and length, enabling engineers to design structures that avoid sudden failure by ensuring the applied forces stay below this buckling threshold.
