An Overview of Fatigue Testing Systems for Metals under Uniaxial and Multiaxial Random Loadings

This paper presents an overview of fatigue testing systems in high-cycle regime for metals subjected to uniaxial and multiaxial random loadings. The different testing systems are critically discussed, highlighting advantages and possible limitations. By identifying relevant features, the testing sys...
