Abstract:Robustness, reliability, optimisation and Finite Element simulations are of major importance
to improve product quality and reduce costs in the metal forming industry. In this paper,
we review several possibilities for combining these techniques and propose a robust optimisation
strategy for metal forming processes. The importance of including robustness during optimisation
is demonstrated by applying the robust optimisation strategy to an analytical test function: for constrained
cases, deterministic optimisation will yield a scrap rate of about 50% whereas the robust
counterpart reduced this to the required 3 c reliability level.
