In the present work, the simulation analysis of automobile energy-absorbing components was carried out using Finite Element (FE) method. The numerical simulations were carried out using the software LS-DYNA. Automobile energy-absorbing components usually were made of a metal thin walled tube. In the paper, several types of material properties were studied and compared. Results show that the material properties have influence to automobile energy - absorbing components crashworthiness.

Keywords: Energy-absorbing components, finite element analysis, material properties, strain rate, yield strength.
