Modeling and Computational Aspects of Sheet Metal Forming
Mathematical modeling of sheet metal forming processes, usually using a finite element method, has been studied intensively in the past few years, and is beginning to find application in industry. There remain, however, formidable difficulties to be overcome, including inadequate descriptions of nonlinear, anisotropic plasticity, excessive computational costs (especially for geometrically complex parts), and lack of robustness of conputational methods. The speakers in this minisymposium will address these and other issues and will illustrate some industrial applications.
