In stability theory, the four cases of Euler buckling represent the elastic flexural buckling of straight bars. Above a specific load – the buckling load – a loss of stability occurs and the bar increasingly changes shape. The axis of the bar is deflected laterally.
Euler describes four cases for the buckling of an elastic bar with central application of compressive force and various methods of support.
Sci-tech Demonstration of Euler Buckling Model MT 033 demonstrates the four cases of Euler buckling.
