TL;DR: The low-cycle fatigue behavior of SUS304-HP austenitic stainless steel was investigated systematically using tension-compression cycling under fully reversed total strain amplitude control conditions at room temperature in laboratory air.

TL;DR: In this paper, a simplified thermodynamics analysis of cyclic plastic deformation is performed in order to establish an energy transition relation for describing the elastic-plastic stress and strain behavior of the notch-tip material element in bodies subjected to multiaxial cyclic loads.

TL;DR: In this article, a physical relationship between Neuber's rule and the equivalent strain energy density (ESED) method is found, where the dissipation of the plastic strain energy at the notch root is neglected in ESED method.

TL;DR: In this article, a series of experiments, including constant amplitude low-cycle fatigue tests, post-fatigue tension to failure tests, LOM (TEM) observations, and SEM examinations, were performed at room-temperature to investigate the effects of low-cycled fatigue damage on the static mechanical properties, microstructures and fracture behavior of 304 austenitic stainless steel.

TL;DR: In this paper, a method for measuring microhardness is used to investigate the surface damage evolution of cyclically loaded annealed 16Mn steel, and a probability expression for a fatigue damage variable is proposed and applied in the discussion of the surface degradation evolution of annaled 16mn steel during fatigue.
