Abstract
The objective of this study is to evaluate the influence of the hydro-forming process and the effect of strain rate on crash performance and develop a modeling approach to improve the accuracy of crash prediction. Work hardening, thinning and strain rate effects are investigated in both component and full vehicle analyses to understand their sensitivities. Gages measured and material properties tested from post-formed tubes are compared with hydro-forming simulation results to confirm accuracy of the modeling methodology proposed in the paper. Front crash simulation using strain rate and forming effects are correlated with the test data for both component and full vehicle analyses and conclusion has been drawn from this comparison.
