Abstract
A finite element impact simulation study was performed to gain an insight about the crash test details considering construction tolerance effects of the reinforcement of posts in an open-type guardrail system. Accuracy of the simulation was verified using qualitative and quantitative comparisons with a full-scale crash experiment of trucks and cars. Subsequent simulation results present that the improved model performs much better in containing and redirecting the impacting vehicle in a stable manner. The numerical results for various parameters are verified by comparing different models with dynamic responses and passenger safety evaluations determined in the barrier from the crash simulation.
