In this paper, recent optimisation techniques have been used to improve crash performance of a thin-walled tube considering influence of the forming history. In the optimisation study, weight and amount of the energy absorption of the thin-walled tubes are chosen as objective function and constraint, respectively. Radial basis functions (RBFs) metamodelling technique was used to approximate the structural responses selected in crash and forming analyses. The performances of recent optimisation

The lowest mass of the components is obtained at 1000 function evaluation number (FEN) using hybrid GSA. Reference to this paper should be made as follows: Karagöz, S. and Yildiz, A.R.
