Buckling: Failure Mode Compressive Stress

Buckling occurs when a structural member under compressive stress suddenly deflects sideways due to an instability, even if the stresses are below the material's failure point. As load increases on a column, it will eventually buckle at a critical point. Further loading after buckling can cause unpredictable deformations and possible collapse, though the member may still support the original buckling load. Buckling is a mathematical bifurcation where, above a critical load level, the structure can exist in one of two equilibrium states: laterally compressed or deformed.

Buckling

In science, buckling is a mathematical instability that leads to a failure mode.


When a structure is subjected to compressive stress, buckling may occur. Buckling is
characterized by a sudden sideways deflection of a structural member. This may occur
even though the stresses that develop in the structure are well below those needed to
cause failure of the material of which the structure is composed. As an applied load is
increased on a member, such as a column, it will ultimately become large enough to cause
the member to become unstable and it is said to have buckled. Further loading will cause
significant and somewhat unpredictable deformations, possibly leading to complete loss of
the member's load-carrying capacity. If the deformations that occur after buckling do not
cause the complete collapse of that member, the member will continue to support the load
that caused it to buckle. If the buckled member is part of a larger assemblage of
components such as a building, any load applied to the buckled part of the structure
beyond that which caused the member to buckle will be redistributed within the structure.
In a mathematical sense, buckling is a bifurcation in the solution to the equations of static
equilibrium. At a certain point, under an increasing load, any further load is able to be
sustained in one of two states of equilibrium: a purely compressed state (with no lateral
deviation) or a laterally-deformed state.
