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

Effect of nitriding on low-cycle fatigue properties

International Journal of Fatigue, 1997
Abstract Nitriding is a thermochemical surface treatment that is often utilized to improve the fatigue strength of mechanical elements. In fact it is well known that, after the treatment, owing to the formation of a nitrided external layer and a field of residual stresses that are compressive on the surface, the high-cycle strength is strongly ...

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 ...

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 ...

Low Cycle Fatigue of Cast Austenitic Steel

2017
Cast austenitic stainless steel 1.4848 is used to manufacture automotive exhaust system components. Low cycle fatigue (LCF) of 1.4848 austenitic steel was investigated through strain controlled fatigue testing at strain rates of 0.02/s, 0.002/s, and 0.0002/s in the temperature range from room temperature (RT) to 900°C.

Low cycle fatigue of aluminum foam

Materials Science and Engineering: A, 2009
Abstract An experimental investigation into the tension-compression fatigue behavior and failure mode of closed-cell aluminum foam was conducted. Alporas aluminum foam specimens, of 8.7% average relative density, were subjected to fully reversed axial fatigue at nominal total strain amplitudes ranging from 0.05% to 0.5%.

LOW‐CYCLE FATIGUE OF MATERIALS FOR SUBMARINE CONSTRUCTION

Naval Engineers Journal, 1963
<div class="htmlview paragraph">Materials for submarine construction were investigated to determine their low-cycle flexural fatigue behavior. Botl ferrous and nonferrous materials, including five steels with yield strengths of 40,000-230,000 psi, five nickel base, six aluminum base, and three copper base alloys were used in the study ...

Equibiaxial Low Cycle Fatigue

2003
The major fatigue loading for a turbocharger intercooler on a lorry engine is the once per day start up and cool down cycle. The intercooler is made from an aluminium alloy whose properties are given below. The critical location for fatigue failure is known from finite element models to experience an equibiaxial, in-phase proportional strain cycle ...
