Numerical Simulation of a Stretch Drawn Autobody: Part II - Validation Versus Experiments for Various Holding and Drawbead Conditions 920640
Two papers describe an innovative joint simulation and experimental activity, established in order to evaluate a CAE approach for tool design optimization in sheet metal forming. The main target is to assess the CAE validity with respect to sheet behavior modelling, influence of holding and restraining conditions (including drawbeads), and the reproduction by simulation of local sheet elongation and thickness. A stretch drawn autobody component was taken as the practical application of this evaluation (Pre-Industrial Case).
This is Part 2, describing in more details the autobody component of interest, the experimental measurements made, and the results of the simulations. Very good agreement was found when comparing experimental and numerical elongations along the critical lines. Also, the simulation was able to accurately reproduce complex stamping difficulties, such as for the development and squeezing of under punch bulges.
