Abstract
For the design of suspension components the behavior under extreme, special events, loading as well as the durability under operational usage are decisive. While the behavior under extreme loading depends on the component stiffness, which is mainly influenced by the design and the material mechanical properties, durability is influenced by the fatigue properties under operational loading. For this purpose the fatigue properties on aluminum alloys 5083 and 6009 using different types of stresses (tension, shear, torsion, bending), loading-time histories (constant and variable amplitude loading) and welding technology were investigated and will be presented in this paper.
