%X In this study, a frontal collision scenario (rigid wall test) is simulated in a computer environment using a half vehicle model for two different sheets of steel that are frequently used in automotive industry. The effects of materials, namely FEE340 steels in HSLA (High-Strength Low Allow) family and DP600 steels in DP (Dual Phase) family compared as front collision rails on crash performance of a vehicle. Front bumper cross member, crash box and collision rail in the model were designed using Siemens NX software. The pre-processing stage of collision elements before the dynamic analysis was carried out using Altair Hypermesh software. Abaqus software was used to create the dynamic analysis scenario of the model and to solve the analysis. The amount of energy absorption by each element, the total displacement, the level of the load transferred to the passenger compartment and the crush force efficiency (CFE) results were obtained from the simulations. According to the simulations results, although the CFE coefficients of FEE340 and DP600 materials are close, when the FEE340 material was used, the force transferred to the passenger compartment was 32% less, and the total displacement was 11% higher
