Multiscale TRIP-based investigation of low-cycle fatigue of polycrystalline NiTi shape memory alloys

International journal of plasticity, 2019
In this paper, a multiscale investigation of fatigue crack initiation in shape memory alloys (SMAs) based on Transformation Induced Plasticity (TRIP) is presented. A mechanism for fatigue crack initiation during cyclic stress-induced phase transformation

Low cycle fatigue behavior of precipitation-strengthened Cu-Cr-Zr contact wires

International Journal of Fatigue, 2020
The low cycle fatigue behavior (Δet/2 = 0.4–1.0%) of a Cu-Cr-Zr alloy strengthened with nanoscale precipitates has been tested at room temperature. The results showed that cyclic softening occurs under all Δet/2 after cyclic hardening. However, the Cu-Cr-

Low Cycle Fatigue Counter

Aircraft Engineering and Aerospace Technology, 1980
The modern aircraft gas turbine engine produces power on demand hour upon hour and day in, day out. It is one of the most extensively used types of high‐speed rotating machinery as well as one of the most efficient converters of fuel into thrust. Reliability and long life with minimum maintenance depend on efficient monitoring of engine performance and

Low cycle fatigue properties of Ti-6Al-4V alloy fabricated by high-power laser directed energy deposition: Experimental and prediction

International Journal of Fatigue, 2019
The low cycle fatigue (LCF) properties of Ti-6Al-4V parts fabricated by high-power laser directed energy deposition were investigated. The results show that the parts after solution treatment and aging exhibit superior LCF lives to those of other ...

Microstructure analysis and low-cycle fatigue behavior of spray-formed Al–Li alloy 2195 extruded plate

Materials Science & Engineering: A, 2019
Microstructure and low-cycle fatigue behavior of spray-formed Al–Li alloy 2195 extruded plate were investigated in this work. The spray-formed alloy after hot extrusion experiment was treated with solid solution treatment and artificial aging ...

Initiation from Low Cycle Fatigue to Gigacycle Fatigue

Advanced Materials Research, 2014
This paper is devoted to the initiation of fatigue crack in Armco iron from low cycle fatigue to gigacycle fatigue. It is shown that the basic mechanisms of initiation are very similar from a physical point of view: PSB and Grain boundary cracking. But the mechanical aspect is specific in LCF and in GCF.

Low-Cycle Fatigue Test on Stud Shear Connectors

Journal of Structural Engineering, 1997
In steel-concrete composite beams particular attention has to be paid to the fatigue phenomena in the connection. If each part of the structure behaves elastically the problem can be faced with the classical load-life fatigue approach, but for long-span beams, the slip at interface may reach values that involve inelastic deformation of the connector ...

Improvement of low-cycle fatigue resistance in AISI 4140 steel by annealing treatment

International Journal of Fatigue, 2019
The low-cycle fatigue (LCF) behaviour of AISI 4140 steel under annealed and as-received conditions was investigated at room temperature. The annealing treatment causes a marked decrease in mechanical strength but an increase in plastic energy and ...

Strain-Based Fatigue Analysis—Low Cycle Fatigue

2012
When the plastic component the cyclic strain cannot be neglected and, indeed, prevails over the elastic one, stresses are no longer uniquely determined and must be put aside in the fatigue analysis. This is the case of structural discontinuities in general and of notches, in particular, where local strains can go well beyond the elastic limit of the ...
