Buckling

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

Theoretically, buckling is caused by a bifurcation in the solution to the equations of static equilibrium. At a certain stage under an increasing load, 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.

Buckling is characterized by a sudden sideways failure of a structural member subjected to high compressive stress, where the compressive stress at the point of failure is less than the ultimate compressive stress that the material is capable of withstanding. Mathematical analysis of buckling often makes use of an "artificial" axial load eccentricity that introduces a secondary bending moment that is not a part of the primary applied forces being studied. 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 is said to have buckled. Further load will cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capacity. If the deformations that follow buckling are not catastrophic the member will continue to carry 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 structure beyond that which caused the member to buckle will be redistributed within the structure.

Buckling (fish)

A buckling is a form of hot-smoked herring similar to the kipper and the bloater. The head and guts are removed but the roe or milt remain. They may be eaten hot or cold.

Origin

The word may come from the German Bückling or the Swedish böckling, both words denoting a hot-smoked variety of the kipper.

Bucklings, bloaters and kippers

Buckling is hot-smoked whole; bloaters are cold-smoked whole; kippers are split and gutted, and then cold-smoked.
