This chapter discusses common approaches for fatigue strength assessment of welded joints. These are based on different types of stresses, which are described in detail at the beginning. Subsequently, several factors affecting the fatigue strength are discussed with a special focus on welded joints, which are considered in the approaches in different ways. Then the chapter outlines S-N approaches using different types of stress for the S-N curves together with a damage accumulation law. The alternative crack propagation approach is only briefly addressed, being the subject of other chapters.
