|Abstract:||<p>Discontinuous yielding in the form of Lüder's bands in frequently observed in tensile testing to mild steel sheets. In these materials, instability or kinking may or may not be observed in bending operations and various theories have been proposed to relate the bending and tensile phenomena.</p> <p>In this work, an extensive experimental investigation was performed on five samples of low carbon sheet steels. The main objective was to develop a new analytical model, based on the uniaxial tensile stress-strain curve that will predict the behaviour of these materials in pure bending. Two models appeared possible and the experiments performed suggested that one of these is an appropriate model for steels of this kind.</p>|
