Structural durability is understood as the ability of a structure or a component to withstand cyclic, quasistatic, impact and environmental loads that occur during service. Part of the spectrum can exceed the high-cycle constant amplitude fatigue strength in order to enable lightweight design; the required service duration can still be fulfilled also under consideration of special events. For establishing a structurally durable construction, the design engineer has to adjust the strength properties in the critical, i.e. highly loaded, regions to the occurring local service stresses/strains in the most effective manner possible for determining the component dimensions. This can be accomplished through suitable design and manufacturing as well as adequate material
