Abstract

As more metallic alloys are introduced in engineering structures, the demand for the proper utilisation of their nonlinear stress-strain relationship is increasing. This paper discusses the inelastic buckling of members from such materials with a special focus on ferritic stainless steels. Here we introduce an alternative approach for the overall stability of members that considers material nonlinearity, namely the strain hardening parameter n. The suitability of the new model is verified by regression analysis in comparison with the commonly used standard calculations. The analysis results show that the present approach could be applied successfully in flexural, flexural-torsional and lateral-torsional buckling.
