A Study on the Low Cycle Fatigue Behavior of the Steel for

Abstract:Giga-cycle fatigue behavior of notched specimens with stress concentration factor, Kt of 1.5, 2.0 and 2.5 for 0.65 mass% carbon matrix high speed steel, YXR3 with Rockwell C scale hardness number of 60.7 is investigated. The higher the stress concentration factor the lower the giga-cycle fatigue Comprehensive Assessment of Low Cycle Fatigue Behavior of May 08, 2020 · The effects of temperature on low cycle fatigue (LCF) behavior of Superni 263 superalloy in the solution annealed plus aged state were examined between 298 and 1023 K. The initial microstructure consisted of intragranular spherical (22 nm), intergranular M23C6 carbides and a few un-dissolved primary MC particles. Strain-controlled LCF tests were performed at a strain rate of 103

Effect of anisotropy and texture on the low cycle fatigue

The alloy showed a strong basal texture indicating that most of the basal planes of hexagonal close-packed lattice were located parallel to the rolling direction. Specimens loaded parallel to the rolling direction (RD) were easy to yield in

Effects of environment on the low-cycle fatigue behavior

OSTI.GOV Technical Report:Effects of environment on the low-cycle fatigue behavior of Type 304 stainless steel Experimental Investigation on the Creep and Low Cycle This paper experimentally investigated the creep and fatigue behaviors of a low-pressure turbine (LPT) blade with 600 hours of service using a novel test system. Pure low cycle fatigue (LCF), pure creep and creep-fatigue interaction (CFI) experiments on the full

Extremely Low Cycle Fatigue Behaviors of Anti-Seismic

Fatigue (LCF) behaviors. To distinguish this very-low-cycle regime from larger cycle parts of the LCF region, the fatigue failure at very small number of cycles (<100 cycles) is termed as extremely low cycle fatigue (ELCF) [3-8]. Extremely low cycle fatigue, with the fatigue life of less than 100 cycles, is the extremely behaviour of Low Cycle INFLUENCE OF :CREEP DAMAGE ON THE LOW CYCLE has generated a need for thermal fatigue data on these materials in a hard vacuum environment. The present study was therefore undertaken to characterize the thermal fatigue behavior of T-Ill and ASTAR 811C in vacuum using in-dependently programmed strain and temperature cycles in the range of h00 to 2lO0°F (478 to 1422°K).

Low cycle fatigue behavior of AlSi10Mg(Cu - osti.gov

Oct 15, 2018 · Effect of isothermal and non-isothermal aging on the low cycle fatigue behavior of an AlCuMgSi forging alloy Mechanism study on the low cycle fatigue behavior of group Nov 01, 2017 · According to the low cycle cyclic analysis results, the fatigue damage initiated at the bottom point of the stud root section in the push load direction, which can be called the fatigue critical point. The low cycle fatigue life reduction of group studs, which was evaluated by the analysis results and the introduced multi-axial fatigue damage criterion, can be explained by the uneven cyclic tensile strain and stress distributions on every individual fatigue

Volume Effects on the Fatigue Behavior of Additively

affect the fatigue behavior of small parts as well as large parts. Previous research has shown there could be a size effect on the fatigue behavior of additively manufactured Ti-6Al-4V parts in the asbuilt condition- [3]. This could result from surface roughness in which large diameter parts built diagonally were better able to dissipate heatAn Investigation of the Mechanical Fatigue Behavior of 9 Some notable studies on modelling the fatigue behavior of lattice or cellular structures include Huang and Liu, [6, 7] and10 Masoumi Khalil Abad et al. [5]. Huang and Liu [6, 7] have developed 11 fatigue models for open-cell foams and honeycomb lattices for crack propagation, as well as high 12 cycle and low cycle fatigue. Their analyses were
