Whether your product is a consumer item, a machine, a vehicle or a building, it’s fatigue life has to be considered. Designing it for normal use load cases is not enough to ensure it will fulfill its function throughout its designed life. It is also not economically viable or competitive anymore to simply design with large safety factors or to crudely over design it. Products need to fulfill their purpose for the duration of its intended life and no longer than that to be competitive.

To strike a balance between warranty claims, safety risks, brand name awareness and an economical and competitive product, engineers have to evaluate a product’s fatigue life.
