Chapter 5: Buckling

Chapter overview

We often define failure as the material reaching the yield or ultimate tensile strength. But there is another kind of failure that we haven’t considered; one where the material fails below the yield stress: buckling.

In this chapter we’ll be looking at the following aspects of buckling:

• C5.1 Euler’s Buckling Formula - calculating the critical load before buckling
• C5.2 Secant Formula - used to determine the maximum deflection and stress under a buckling load
