ABSTRACT

The buckling strength of members from metallic materials is, to some extent, governed by their nonlinear strain-hardening behavior (Rasmussen & Rondal 1997). Especially in the case of cold-formed stainless steels the large variety of stress-strain diagram shapes can be achieved by combining different material grades and fabrication methods. While the proper experimental investigation yields always credible results, it is long and expensive process. Numerical calculations can efficiently supplement the experimental program with additional data or completely replace it.
