Buckling failure modes
Webbuckling, Mode of failure under compression of a structural component that is thin ( see shell structure) or much longer than wide (e.g., post, column, leg bone). Leonhard Euler first worked out in 1757 the theory of why such members buckle. http://ffsdesign.com/site/2024/09/14/pipeline-global-buckling-walking-consequences-mitigations/
Buckling failure modes
Did you know?
Buckling is a failure mode in pavement materials, primarily with concrete, since asphalt is more flexible. Radiant heat from the sun is absorbed in the road surface, causing it to expand, forcing adjacent pieces to push against each other. If the stress is sufficient, the pavement can lift and crack without warning. See more In structural engineering, buckling is the sudden change in shape (deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear.

WebBuckling failure occurs when the cross-section of the column is small in comparison with its height. The buckling takes place about the axis having minimum radius of gyration or least moment of inertia.
