Thermographic analysis in ultrasonic fatigue tests [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2006 ABSTRACTThree kinds of alloys used in the automotive industry for structures and engine components are subjected to very high cycle fatigue damage during working service. In the study, fatigue damage progression of the three kinds of alloys was investigated in the very high cycles fatigue regime by means of thermographic analysis.

A Novel Ultrasonic Fatigue Test and Application in Bending Fatigue of TC4 Titanium Alloy
Materials, 2022 The very high cycle fatigue (VHCF) problems of thin-plate structures are usually caused by high-frequency vibrations. This paper proposes an accelerated fatigue test method based on ultrasonic loading technology in order to develop a feasible bending testing method and explore the bending fatigue characteristics of thin-plate structures in the VHCF ...

Cruciform specimens' experimental analysis in ultrasonic fatigue testing [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2019 AbstractIn this paper, two special aluminium cruciform specimens are designed and tested in an ultrasonic fatigue machine. They were designed based on Single‐Input‐Multiple‐Output (SIMO) modal analysis to induce in‐plane biaxial stress combinations (in‐phase tension‐tension [T‐T] and out‐of‐phase compression‐tension [C‐T]) when at resonance at 20 kHz ...

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

Ultrasonic fatigue tests on the Inconel alloy 718
Procedia Structural Integrity, 2020 Abstract Ultrasonic fatigue tests were carried out on the Inconel alloy 718 on pre-corroded and specimens without pre-corrosion. At high applied stress (up to 746 MPa) the specimens without pre-corrosion show fatigue endurance higher compared with the pre-corroded specimens with a factor of 10; whereas at low stress level (close to 510 MPa), the ...
