Statistical Analysis and Robust Optimization of Forming Processes and Forming-to-Crash Process Chains
Source abstract
Abstract
In this paper, a novel strategy for statistical analysis and multi-objective robust design-parameter optimization of forming processes as well as forming-to-crash process chains is discussed and results presented for a ZStE340 metal blank of a B-pillar. The strategy comprises both physical experiments and numerical simulation and is built upon a novel material and damage model as well as several software tools which allow for an efficient sensitivity, stability and robustness analysis, even for simulation results on highly resolved grids.
