| Abstract Scope |
A PID controller was implemented in FEM platform as a user subroutine instead of a sophisticated and expensive control system implemented in a tube hydroforming machine to numerically generate the required boundary conditions, axial feed and pressure profiles, based on proportional strain path at the pole of the bulging tube in the FEM simulations. The generated boundary conditions can directly be used in free tube bulging experiments to generate different deformation modes for tubular material characterization based on accumulated plastic work equivalency. It was also shown that the numerical algorithm developed works accurately for isotropic and anisotropic yield functions. In this study von-Mises and Hill’s 1948 were used as the material models. |
