Buckling - Limit Point Vs Bifurcation Buckling

Limit Point Vs Bifurcation Buckling

Bifurcation buckling is sometimes called Euler buckling even when applied to structures other than Euler columns. As the applied load is increased by a small amount beyond the critical load, the structure deforms into a buckled configuration which is adjacent to the original configuration. For example, the Euler column pictured will start to bow when loaded slightly above its critical load, but will not suddenly collapse.

In structures experiencing limit point instability, if the load is increased infinitesimally beyond the critical load, the structure undergoes a large deformation into a different stable configuration which is not adjacent to the original configuration. An example of this type of buckling is a toggle frame (pictured) which 'snaps' into its buckled configuration.

Famous quotes containing the words limit and/or point:

    The only limit to our realization of tomorrow will be our doubts of today. Let us move forward with strong and active faith.
    Franklin D. Roosevelt (1882–1945)

    Competition has been shown to be useful up to a certain point and no further, but cooperation, which is the thing we must strive for today, begins where competition leaves off.
    Franklin D. Roosevelt (1882–1945)
