Abstract

A tutorial exposition is given of methods for calculating the inelastic buckling stress of specimens tested in accordance with ASTM Standard E 9 on Compression Testing of Metallic Materials at Room Temperature. The recommended round specimen sizes will buckle inelastically for all non-brittle metals, but ASTM E 9 refers only to Euler elastic buckling. An inelastic buckling relation based upon the tangent modulus is given, and methods of calculating the inelastic buckling stress are demonstrated.
