A solid rod has a diameter of 20 mm and is 600 mm long. It is made of a material that can be modeled by the stress–strain diagram shown in the figure below. If it is used as a pin-supported column, determine the critical load.
Solution
Radius of gyration is
Slenderness ratio
Critical stress from Euler’s formula for K=1 pinned at two ends.\
Assuming that critical stress is in the elastic region σ_crit≤σ_pl=100MPa
σ_crit=6.847*〖10〗^(-4)*100 GPa=68.47MPa≤σ_pl=100MPa
