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

Experimental methodology of study of damage initiation and development in textile composites in uniaxial tensile test [PDF]
, 2008 Damage in textile composites is closely connected with the internal micro- and meso-geometry of the reinforcement, and reveals features, which are not present in the damage processes in classical laminates. This paper proposes a test sequence intended to

ULTRASONIC ATTENUATION IN STEELS DURING FATIGUE [PDF]
Le Journal de Physique Colloques, 1985 The change of ultrasonic attenuation Ɗα as a function of fatigue cycle number n correlates well with the length of fatigue crack. A depinning model of dislocations with kinks is suggested to interpret the experimental results.

Ultrasonic needles for bone biopsy [PDF]
, 2017 Bone biopsy is an invasive clinical procedure where a bone sample is recovered for analysis during the diagnosis of a medical condition. When the architecture of the bone tissue is required to be preserved, a core-needle biopsy is taken.

Experimental and numerical polar scans of several anisotropic materials using pulsed and harmonic ultrasonic beams [PDF]
, 2011 Ultrasonic non-destructive testing is a well known technique in present days, in which the C-scan is the most wide spread. Though, because of the inherent limitations of most methods to quantitatively characterize (damaged) composite materials, the quest

Measurement of interface pressure in interference fits [PDF]
, 2005 When components such as bearings or gears are pressed onto a shaft, the resulting interference induces a pressure at the interface. The size of this pressure is important as many components fail because fatigue initiates from press-fit stress ...

ULTRASONIC ATTENUATION IN STEEL DURING FATIGUE
Acta Physica Sinica, 1985 The fatigue crack length a and the changes of ultrasonic attenuation △α at frequency 10 MHz 011 compact test sample of 30CrMnSiNi2A steel have been simutane-uosly measured as a function of fatigue cycle number N. It was shown that the △α(N) curve was in good response to the a(N) curve and the △α was traced out during the period of crack nucleation. The
