Abstract

Structural steels need to demonstrate certain ductility in order to be used in build-ings design. Fulfilling these criteria of design codes may be difficult especially for new high-strength steels where ductile fracture of tensile coupons appears at relatively low deformation. The goal of our study is to develop a calculation method of alternative ductility limits for structural details in a particular design situation. Such limits might be less demanding. Appli-cation of the method to a large variety of material models resulted in a simple criterion for the standard coupon test, the minimum distance between the uniform elongation and the coupon failure. This distance is called "necking capacity" of a tensile coupon in our paper.
