Product designers worldwide are confronted with highly competitive though conflicting demands to deliver more complex products with increased quality in ever shorter development cycles. Optimizing design performance with purely test-based approaches is no longer an option and numerical simulation methods are widely used to model, assess and improve the product design based on virtual prototypes. Functional performance attributes such as body strength, NVH, VAM, durability, crashworthiness … [3, 9, 22] can already be optimized before entering the expensive test phase. A new paradigm of mechanical testing as essential enabler in the virtual prototype optimization process resulted. Combined advances in test and simulation push the design envelope to shorter and higher quality product development cycles [21].
The use of the Finite Element (FE) method is widely established for the virtual prototyping phase. A major issue is the presence of uncertainty and variability in the material and geometrical properties and manufacturing processes [18, 26]; their effect on the performance cannot be predicted from a single FE analysis.
