Investigation of very high cycle fatigue by thermographyc method [PDF]

Fracture and Structural Integrity, 2014
Nowadays, many components and structures are subjected to fatigue loading with a number of cycles higher than 107. In this scientific work, the behaviour of two kinds of tool steel was investigated in very high cycle fatigue regime.

Very High Cycle Fatigue of Welds: A Review

Metals, 2023
The design life of welded structures and components extends into the very high cycle fatigue (VHCF) regime across various applications. However, the availability of data on the fatigue behaviour of welded joints in the VHCF regime is limited ...

Scaling of damage mechanism for additively manufactured alloys at very high cycle fatigue [PDF]

Scientific Reports
A comparative analysis of fracture mechanisms in high- and very high- cycle fatigue (HCF, VHCF) regimes was carried out based on the results of multifractal analysis of the fracture surfaces of additively manufactured 316L stainless steel samples.

Titanium Alloy Materials with Very High Cycle Fatigue: A Review [PDF]

Materials (Basel)
As the reliability and lifespan requirements of modern equipment continues to escalate, the problems with very high cycle fatigue (VHCF) has obtained increasingly widespread attention, becoming a hot topic in fatigue research. Titanium alloys, which are the most extensively used metal materials in the modern aerospace industry, are particularly prone ...

Effect of Low Cycle Fatigue Predamage on Very High Cycle Fatigue Behavior of TC21 Titanium Alloy. [PDF]

Materials (Basel), 2017
The effect of low cycle fatigue (LCF) predamage on the subsequent very high cycle fatigue (VHCF) behavior is investigated in TC21 titanium alloy. LCF predamage is applied under 1.8% strain amplitude up to various fractions of the expected life and subsequent VHCF properties are determined using ultrasonic fatigue tests.

Very high cycle fatigue strength and crack growth of thin steel sheets [PDF]

Fracture and Structural Integrity, 2016
For basic observations or for industrial applications it is of interest to use flat specimens at very high frequency in the gigacycle regime. In this work, thin flat sheet, with 1.2 mm thickness of a complex phase ferrite-martensitic steels were ...

Fretting Fatigue Behaviour of Alloy Steel in the Very High Cycle Region [PDF]

MATEC Web of Conferences, 2019
It is well known that fretting fatigue strength is much lower than the fatigue strength of smooth specimens and the fatigue limit disappears. Many studies on fretting fatigue have been reported but most of the studies have not cover fatigue properties in
