What is Critical Buckling Load?

Buckling is a sudden lateral failure of an axially loaded member in compression, under a load value less than the compressive load-carrying capacity of that member. The axial compression load corresponding to this mode of failure is referred to as critical buckling load.

What does Buckling mean?

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.
