A cantilever graphene column has a stress-strain relationship shown in Eqn.1. The section of the column is shown in Fig. 4. The length of the column is 5 mm and buckling in the weak (z) axis is fully prevented. It is required to: (1) Calculate the critical buckling force (Ner) for the column using the tangential modulus theory. (2) Why does the tangential modulus theory typically underestimate the critical buckling load? What is the solution for this issue? o=1000-2000ɛ² (GPa) (Eqn. 1) 4.0 1.0 1 4.0 12 -y 1.0 Fig.4. Graphene column (mm).
