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.
