The design of fatigue-limited automotive components is inherently complex. Inadequate understanding and control of this complexity can result in a failure to satisfy the design requirements within the available budget or timeframe. By documenting case studies of fatigue-limited design for the automotive industry, including the authors’ experience, it is intended to develop a conceptual model of the feasible product development paths for fatiguelimited design. Investigation of the feasible product development paths generates a qualitative checklist of the major risks of design failure for a given design scenario, allowing appropriate strategies of risk management to be established before committing to a design project. Risk management strategies employed by a range of industries involved in fatigue-limited design will be identified and examined.
