The simplified buckling criterion applied to plates with partial edge loading

The development is outlined of the first author's Simplified Plate Buckling Criterion which is based on nonlinear theory. For the case of uniaxial, symmetric, partial-edge loading, the work of the first author is compared with the numerical solutions of the second author and with the results of Yamaki by energy theory. The Simplified Criterion gives results with a minimum of computational effort well within practical accuracy requirements.
