Buckling and bending are similar in that they both involve bending moments. In bending these moments are substantially independent of the resulting deflections, whereas in buckling the moments and deflections are mutually inter-dependent - so moments, deflections and stresses are not proportional to loads.

buckle means bending
unsymmetrical bending
you may have 2 kinds of failures. there is the buckling and the bending. in the bending there is compression and tension, while in the buckling there i torsion and shear. if the beam is restrained but not stiffened you may have Lateral Torsional Buckling, but if it is restrained and stiffened throughout, then you will have Tension Field Action and this would result in a higher load durability.
a fold
Buckling Load: It is the highest load at which the column will buckle. Crippling Load: It is the max load beyond that load, it cant use further it becpomes disable to use. The buckling Load < The Crippling Load Safety load= Crippling Load/ Factor of safety
Main difference between local and overall buckling related to distortion of the overall system geometry. Local buckling does not cause distortion of the overall geometry, usually local buckling seems on short (channel or angle) compression members (excessive loaded and material related problem). On the other hand overall buckling causes distortion, we can give example as plastic ruler compressed by fingers . There is equation on buckling developed by Euler.
Buckling; shriveling, bending, or curling from heating or pressure. (heating, in this case)
The elastic bucklingoccursfor slender columns that have a large slenderness parameter(KL/R) before any yielding in the materials. While the inelastic buckling occurs for intermediate columns that have amoderate(KL/r) ratio and the failure occurs by both the buckling and part of the materials yieldingsimultaneously
This is known as a fold. The process therefore is known as folding or more technically ductile deformation.
Gerald Walter Corney has written: 'The effect of stiffener dimensions on the buckling of webplates subjected to bending'
Column is a member which is designed for taking buckling also in addition to transmit the load to the foundation, where as pillar will not withstand for buckle (slenderness)
short column get failed due to crushing force only while long column got failed due to bending moment as well..
