Recent advances in the ultrasonic polar scan method for characterizing (degraded) fiber reinforced plastics [PDF]

, 2015
The ultrasonic polar scan (UPS) technique originated in the 1980's as a sophisticated method for inspecting composites. However, it is only in recent times that the true capabilities and strengths of the UPS methodology have been evidenced through ...

Experiment-Based Fatigue Behaviors and Damage Detection Study of Headed Shear Studs in Steel–Concrete Composite Beams

Applied Sciences, 2021
Many in-service bridges with steel–concrete composite beams are currently aging and experiencing performance deterioration. Under long-term cyclic loads from traffic on bridges, headed shear studs in steel–concrete composite beams are vulnerable to ...

The application of ultrasonic NDT techniques in tribology [PDF]

, 2005
The use of ultrasonic reflection is emerging as a technique for studying tribological contacts. Ultrasonic waves can be transmitted non-destructively through machine components and their behaviour at an interface describes the characteristics of that ...

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

Interaction of laser generated ultrasonic waves with wedge-shaped samples [PDF]

, 2012
Wedge-shaped samples can be used as a model of acoustic interactions with samples ranging from ocean wedges, to angled defects such as rolling contact fatigue, to thickness measurements of samples with non-parallel faces.

On the Specimen Design, Physical Properties and Geometry Effect on Heat Generation and Thermal Gradient in Ultrasonic Fatigue

Machines
Performing fatigue characterisation is often an expensive task, being both time consuming and expensive. Taking that into account, ultrasonic fatigue testing is an interesting solution, since it can be thousands of times faster than traditional ...
