Abstract

This paper presents a novel strain-based continuum damage mechanics (CDM) model for predicting forming limit curve (FLC) of AA5754 under warm forming conditions. The model is formulated and calibrated based on two different sets of experimental data; isothermal uniaxial tensile data at temperature range of 20-300°C and strain rate range of 0.001-10 s-1 and isothermal FLC data at temperatures range of 20-300°C and forming speeds of 20-300 mm s-1. A good agreement has been achieved between the experimental and numerical results.
