Accelerated Ultrasonic Fatigue Testing Applications and Research Trends

Transactions of the Korean Society of Mechanical Engineers A, 2012
Very high cycle fatigue (VHCF) behavior of aerospace components has emerged much attention due to their long service life. In this study, a piezoelectric ultrasonic fatigue testing (UFT) system has been developed by Mbrosiatec Co., Ltd. to study the high cycle fatigue (HCF) strength of Ti-6Al-4V alloy.

High-Temperature Ultrasonic Fatigue Testing at 1000°C

Advanced Materials Research, 2014
A high-temperature ultrasonic fatigue testing system was developed to evaluate the gigacycle fatigue properties of single-crystal superalloys used in aircraft engine turbine blades. In this development, a commercial ultrasonic fatigue testing machine was considerably modified to achieve high-temperature fatigue testing.

Fatigue Test of Asphalt Mixture and Ultrasonic Forecast

Advanced Materials Research, 2010
The fatigue behavior of the asphalt mixtures beams is experimented by sine wave load, and the fatigue life is predicted by ultrasonic ware theories. Test results show that ultrasonic ware can reflect better fatigue process, and it is an effective method to analyze and forecast fatigue property.

Ultrasonic fatigue tests with stabilized amplitude and controlled temperature

Ultrasonics, 1976
Abstract An attachment for fatigue testing was developed, complementary to a commercially available ultrasonic generator with a power of 200 W. The fundamental improvements are: a control system which stabilizes the fatigue amplitude, and a programming attachment which supplies ultrasonic fatigue pulses in order to prevent undesirable temperature ...

Durability Assessment of Polyoxymethylen Using Ultrasonic Fatigue Testing

Transactions of the Korean Society of Mechanical Engineers A, 2015
부품 및 소재 산업분야에서 최근 고기능, 고성능의 엔지니어링 플라스틱(Engineering Plastic; EP)이 환경기술과 재료기술의 융‧복합기술로서 다양하면서도 핵심적인 역할을 차지하고 있다. 최근 자동차 분야에서는 복합소재로써 내외장재뿐만 아니라 내연기관에 금속소재를 EP 재료로 대체하기 위하여 경량화, 생산성과 함께 기계적 강도, 내약품성, 마찰마모 특성, 내피로성 및 열적 특성 등이 우수한 EP 재료의 새로운 요건을 검토하여 단기 및 중기적으로 플라스틱의 부품 적용 가능성이 커지고 있는 상황이다.

Ultrasonic Testing of Compressor and Turbine Blades for Fatigue Cracks

Aircraft Engineering and Aerospace Technology, 1959
Special probes were developed to test rotor blades for fatigue cracks. These probes utilize ultrasonic surface waves which are highly sensitive to fatigue cracks. The dimensions of the probes were kept small to make possible the testing of blades without the necessity of dismounting.
