Design Challenge

Does the metal yield before or after the structure has buckled and collapsed?  


The material is D50 steel, with a yield stress of 355 MPa (50,000 psi). A vertical load is applied at the mid-point of the beam.

The left hand picture shows the stresses at 10 tonnes load: the metal in the region shown red has yielded. If buckling has occurred, a tell-tale sign is that even though the load was applied vertically, significant horizontal deflection would occur.


The diagram on the right shows what the beam would look like after buckling. Buckling in fact occurs at about 47 tonnes load. Thus this beam would yield before buckling; and the ability of the metal to withstand yielding is the limitation on the design.
