Buckling

A deformation of certain parts of ship, s structure: a bulge bend or other condition of the structure caused by in plane compressive stresses and/or shear forces. Permanent buckling may occur as a result of overloading, overall reduction in thickness due to corrosion, or damage.

Elastic buckling – The result of compressive loading on a prismatic structure that occurs when critical load is within the elastic range (below the load to cause initial yielding).

Elasto-plastic buckling – The result of compressive loading on a prismatic structure that occurs when the critical load is above the load that produces initial yielding.

Lateral buckling – The result of compressive loading on a prismatic structure that occurs when the critical loads is within the elastic range and which involves deformations in the lateral (transverse) direction, usually associated with prismatic sections such as columns.

Snap-through buckling – The near-instantaneous change from one buckled form to another, involving no load increase.
