Today, the inevitability of traffic accidents, the desire to achieve low-cost and lightweight designs, are the three
main conflicting requirements that automotive manufacturers must optimize. The two most important focuses of
these studies are design and material research. In recent years, both lightweight design and crash performance
studies have focused on the use of light metals on vehicles. Magnesium is a metal that has come to the forefront
in the past 10 years for the development of crash performance of vehicle components and the simultaneous
execution of lightweight design. In this study, the development of an energy with magnesium alloys AZ31 and
AM60, which was investigated for minimal damage to drivers and passengers during a frontal collision, was
investigated. The geometry of the energy absorber was developed in the Catia software. The Hypermesh software
as used for crash definitons and the Ls-dyna was used as solver. The strain rate effects are considered with the
Cowper – Symonds model as shown in Equation (1).
