Some remarks on Lode angle and Lode parameter

Abstract In the literature of plasticity, the variables Lode angle and Lode parameter are increasingly used as coordinates to describe the stress space when defining suitable yield or limit conditions ‐ often, however, without any or only alleged reference to the original work of Walter Lode. The present study will attempt to clarify this situation and provide an appraisal and classification of Lode's work.
