A unified expression for low cycle fatigue and extremely low cycle fatigue and its implication for monotonic loading

International Journal of Fatigue, 2008
Abstract It is well-known that the empirical Manson–Coffin law tends to over-predict the cyclic life under extremely low cycle fatigue condition. In the present paper, a new unified expression is proposed to overcome this shortcoming. By introducing an exponential function, this new expression is capable of capturing the cyclic life over the entire ...

Low-cycle fatigue behavior and deformation mechanisms of a dual-phase Al0.5CoCrFeMnNi high-entropy alloy

International Journal of Fatigue, 2022
We uncover the low-cycle fatigue response and deformation mechanisms of a dual-phase Al 0.5 CoCrFeMnNi high-entropy alloy (HEA) by comparing to CoCrFeMnNi HEA.

Effect of Work‐Hardening Mechanisms in Asymmetrically Cyclic‐Loaded Austenitic Stainless Steels on Low‐Cycle and High‐Cycle Fatigue Behavior

Steel Research International, 2020
Dislocation characteristics and deformation‐induced martensite (DIM) transformation in an asymmetrically cyclic‐loaded metastable type 304 stainless steel (SS) are investigated compared with a stable type 316SS using EBSD and X‐ray diffraction line ...

Low-cycle fatigue properties of bimetallic steel bars after exposure to elevated temperature

Journal of constructional steel research, 2021
The BSB (bimetallic steel bar) has a broad application prospect in RC (reinforced concrete) structures servicing in corrosive environment. To determine seismic resistance of RC structures, it is important to clarify the low-cycle fatigue properties of ...

Experimental and numerical investigations on seismic performance of RC bridge piers considering buckling and low-cycle fatigue of high-strength steel bars

, 2021
In order to promote the application of high-strength steel bars (HSSB) in reinforced concrete (RC) bridge structures, the mechanical properties of HSSB as well as seismic performance of high-strength RC piers were investigated by experimental study and ...

Influence of uniaxial and biaxial pre-straining on the low cycle fatigue performance of DP590 steel

, 2021
The present work aims to examine the low cycle fatigue (LCF) behavior of dual-phase (DP590) steel subjected to different pre-straining (uniaxial and equi-biaxial) paths. The LCF tests reveal all specimens showed continuous cyclic softening throughout the

On the low-cycle fatigue response of CoCrNiFeMn high entropy alloy with ultra-fine grain structure

, 2020
High Entropy Alloys (HEAs) are a new class of multi-component alloys with excellent tensile strength-ductility combination. Their yield strength levels, however, are still low as compared to other high strength materials.

Low cycle fatigue of superalloys

Materials Testing, 2004
Abstract Low cycle fatigue (LCF) of a fourth-generation single-crystal (SC) Ni-base superalloy TMS-138 was studied by comparison with typical third-generation (TMS-75) and second-generation (CMSX-4) Ni-base SC superalloys. TMS-138 exhibits improved LCF behaviour under a condition of the R ratio of 0 at temperatures of 1073 K and 1173 K ...

Probabilistic-based combined high and low cycle fatigue assessment for turbine blades using a substructure-based kriging surrogate model

, 2020
Fatigue assessment for gas turbine blades under combined high and low fatigue cyclic loading is very difficult. In this paper, we propose a probabilistic approach based on a substructure-based kriging surrogate model (SKM) that embeds substructure ...
