Description
Definition and quantification of ductility in reinforcing steels by means of a single parameter has not yet been resolved satisfactorily. This study summarizes the models developed to date and puts forward a new ductility parameter, evaluating the necking deformations generated in the uniaxial tensile test by means of plasticity theory. It also develops the measuring procedure and shows experimental results for the practical applications of this parameter in the field of metallurgy, quality control, and numerical methods.
