The effect of quenching and defects size on the HCF behaviour of Boron steel [PDF]

open access: yes, 2014
This work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically ...

Identification of Fatigue Constants by Means of 3D Method

open access: yesJournal of Mechanical Engineering, 2016
The conventional method for evaluation of the fatigue constants uses one set of experimental data from strain-controlled uniaxial fatigue tests. However, these constants do not ensure the compatibility conditions.

Prediction of Low Cycle Fatigue Lives of Low Alloy Steels.

open access: yesISIJ International, 1996
An assessment of low cycle fatigue data was conducted in this paper with two new life prediction methods. A phenomenological method was developed that accounts for the flow characteristics as a result of loading in terms of dynamic viscosity. The other method is a statistical method known as Diercks equation that has been used as a "first approximation"

Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (HSLA) steel on low cycle fatigue

open access: yesMetalurgija, 2014
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of stabilization is calculated as half ...

TS SPECIMEN LIFE PREDICTION OF HIGH-STRENGTH STEEL RESISTANCE SPOT WELDS

open access: yesJixie qiangdu, 2016
The plastic zone in crack tip influences life prediction result when using crack propagation method to predict fatigue life of spot welds. Most of the methods used to predict fatigue life don’t take plasticity into consideration.

Multiaxial Low Cycle Fatigue of 1070Aluminum under Stress Controlled Non-proportional Loading [PDF]

open access: yes, 2007
This paper describes the low cycle fatigue life of 1070 aluminum under stress controlled multiaxial loading. Proportional loading tests were carried out under combined push-pull and reversed torsion.

Use of elastic stresses for a multiaxial fatigue prediction [PDF]

open access: yesApplied and Computational Mechanics, 2007
A new computational method derived from Papuga PCr multiaxial criterion is presented in the paper. While the PCr criterion is suitable for a comparison of a local multiaxial loading with a fatigue limit, the PCF criterion derived is focused on ...

Effect of variable load on crack initiation microalloyed steel S 690-QL

open access: yesMetalurgija, 2015
The accumulation of damage in the form of initiation and growth of micro-cracks is the first stage of destruction that ends when the merger microcracks form macro cracks. Cracks formed in the cycle number N =104 - 105 are the result of low cycle fatigue.

MODELLING OF STRESS GRADIENT EFFECT ON FATIGUE LIFE USING WEIBULL BASED DISTRIBUTION FUNCTION [PDF]

open access: yes, 2013
In the present paper, a new approach is developed in order to take into account the stress gradient effect on fatigue life of structural components. The proposed approach is based on the weakest link concept in which the shape coefficient of the Weibull ...
