This chapter discusses the basic engineering methods used for fatigue and load analysis. It focuses on some special features that are important when designing for durability. The classic Wöhler and Palmgren‐Miner models for fatigue prediction are presented for loads with increasing complexity. A way to consider fatigue is to view it as caused by load cycles. The chapter discusses different ways to count and plot load cycles. Depending on the use and safety demands of the systems and the components, different design strategies are reviewed. Different kinds of mechanical systems require different load analysis methods, and these principles are outlined. Finally, the role of load uncertainties, caused by scatter and lack of knowledge, in fatigue prediction, is emphasized for various stages of design.
