    Abstract

    Methods for measuring the various parameters of a Lüders band (particularly the width and average strain rate) are developed that use exclusively the load-crosshead displacement curves in tension. Experimental values obtained with these methods agree very well with those determined using extensometers. This allows the identification, in the tensile curve, of the points corresponding to the main events in Lüders band deformation leading to the Type A Portevin-Le Chatelier effect.
