This can result in an over-prediction of fatigue strength (particularly in the high cycle regime) and fatigue limit (Maddox and Zhang, 2008). The alternative is to perform full-scale fatigue testing. The main benefit is that the whole girth weld, in its natural as-welded condition, is subjected to the fatigue load cycle.
This paper presents an overview of fatigue testing systems in high-cycle regime for metals subjected to uniaxial and multiaxial random loadings.

2020, Machines. Fatigue is one of the main causes for in service failure of mechanical components and structures. With the development of new materials, such as high strength aluminium or titanium alloys with different microstructures from steels, materials no longer have a fatigue limit in the classical sense, where it was accepted that they would have ‘infinite life’ . In this chapter, an introduction into the experimental challenges of fatigue testing beyond the classical fatigue limit will be presented. For many applications, strength assessment according to the classical durability (N ≤ 10 7) is no longer sufficient, since increasingly more components are subjected to cyclic loading up to the very high cycle fatigue (VHCF) regime.Instron manufactures tensile, compression, fatigue, impact, rheology, and structural testing machines, testing a variety of materials and range of applications.
