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.

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

Fatigue deformation of 1050 aluminum in ultrasonic fatigue testing.
Journal of Japan Institute of Light Metals, 1995 Ultrasonic fatigue tests have been performed on commercial 1050 aluminum. Internal friction (Q-1) has been measured during fatigue tests and as a function of strain amplitude (e). It is shown that more than 109 cycles test is necessary in order to determine the fatigue limit. Q-1 versus e curves have the inflection points at particular strain amplitude
