Journal ArticleDOI
The low-cycle fatigue, deformation and final fracture behaviour of an austenitic stainless steel
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.
Journal ArticleDOI
Superior fatigue crack growth properties in newly developed weld metal
TL;DR: In this paper, a low transformation temperature welding wire is used to transform from austenite to martensite at about 180°C and finish it at room temperature, which induces a compressive residual stress around the welded part.
Journal ArticleDOI
Further investigation of Neuber’s rule and the equivalent strain energy density (ESED) method
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.
Journal ArticleDOI
Fatigue strength improvement of box‐welded joints using low transformation temperature welding material
TL;DR: In this article, the authors used low transformation temperature welding material which contains 10% Cr and 10% Ni to improve the fatigue strength of developed box welds and found that the expansion of the developed welding material induced the compressive residual stress around welds.
Journal ArticleDOI
Unique fatigue threshold and growth properties of welded joints in a tensile residual stress field
TL;DR: In this article, the authors investigated the fatigue threshold and high growth rate region properties on several kinds of welded joints and found that the unique properties occurred from the fully opened fatigue crack due to the tensile residual stresses.
