New rapid gas-based hot sheet metal forming processes are being invented to manufacture geometrically complex automotive components from lightweight high-strength aluminum alloys. The complexity of the forming processes necessitates a computationally economic yet sufficiently accurate modelling and simulation methodology to ensure a successful simulation-aided process planning for manufacturing complex components. This includes accurate modelling of process characteristics such as large deformations, complex geometrical features, thermo-mechanical and tribological interactions, etc. The current work aims to establish a finite element method (FEM) based simulation methodology for modern gas-based hot sheet metal forming processes. For this purpose, the conventional cross-die geometry is modified with features of some typical automotive components to establish a complex benchmark geometry that covers a broader spectrum of strain states and strain paths. Moreover, a laboratory-scale hot forming test setup for forming the complex benchmark specimen is realized and the preliminary experiments are conducted. The corresponding FE simulation models are developed and experimentally validated. The applicability of the developed benchmark for establishing and validating the models for complex gas-based hot forming processes is demonstrated.
