Magnesium alloys have been widely spread in the automotive industry by their advantage: good mechanical properties, lightweight structure thanks to magnesium’s low density. This paper proposes a methodology to estimate durability of a magnesium alloy AM50 steering wheel. The methodology is based on experimentally determined mechanical and fatigue properties and numerical simulation. The methodology was validated for two types of specimens against experimental fatigue data, and then applied to a steering wheel under torsion, respectively bending loading
