FLOW STRESS - Data and Models



This is the most complete online collection for flow stress data and models. In the first phase over 1200 flow stress models for steels, metals, ferrous and nonferrous alloys are available. The partial models F2, F2F3 and F2F3a, which provide different sets of model parameters for different temperatures, deliver super accurate data. The full model A, B or C each provides a single formula for a given grade, to describe influences of strain, strain rate and temperature, etc.
