High cycle fatigue life of metals

Materials Science and Engineering, 1974
Abstract In eight different materials with U.T.S. ranging from 5 to 80 kpmm−2 the fatigue life curves were determined both for cycling with constant stress amplitude and for cycling with constant plastic strain amplitude in the high cycle region (number of cycles to fracture > 105).

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 ...

Very high cycle fatigue – Is there a fatigue limit?

International Journal of Fatigue, 2011
Abstract The paper gives an overview of the present state of research on fatigue strength and failure mechanisms at very high number of cycles ( N f  > 10 7 ). Testing facilities are listed. A classification of materials with typical S – N curves and influencing factors like notches, residual stresses and environment are given.

Very high cycle and gigacycle fatigue of fiber-reinforced composites: A review on experimental approaches and fatigue damage mechanisms

, 2020
A comprehensive review is conducted on the very high cycle (VHC) and gigacycle (GC) fatigue of fiber-reinforced composite materials. The main objective was to conduct a benchmarking survey of high-frequency fatigue test methods that have been introduced ...

High-cycle fatigue of silver halide infrared fibers

Applied Optics, 1994
The transmission of CO(2) laser radiation by silver halide infrared fibers was measured during cyclic bending of the fibers. High-cycle fatigue of the fibers was investigated. The fibers were found to transmit without significant deterioration after more than 10(7) cycles.

A model for high cycle fatigue

Engineering Fracture Mechanics, 1992
Abstract Failure due to fatigue consists of such macroscopic events as crack initiation and propagation. Microscopic events including microcrack nucleation, microcrack growth and coalescence of some of the microcracks are also important in that such crack interactions can be considered to contribute to the development of a critical defect, i.e.

A probabilistic model for multiaxial high cycle fatigue

Fatigue & Fracture of Engineering Materials & Structures, 2007
ABSTRACTA probabilistic framework developed to model multiaxial high cycle fatigue tests is proposed. Up to now, with a probabilistic point of view (i.e., Weibull law), models account for the stress heterogeneity effect by introducing the concept of effective volume. It is proposed to extend this concept to multiaxial load histories.

High-cycle fatigue and tensile deformation behaviors of coarse-grained equiatomic CoCrFeMnNi high entropy alloy and unexpected hardening behavior during cyclic loading

Intermetallics (Barking), 2019
High entropy alloy (HEA), a new class of materials, has received attention as a substance that can potentially replace conventional alloys. Equiatomic CoCrFeMnNi HEA is an attractive material with excellent strength-ductility combination and corrosion ...
