Ultrasonic fatigue testing in the scanning electron microscope

Materials Testing, 2016
Abstract The continuing trend to increase the performance and durability of machines requires the use of materials, whose structural integrity must be ensured far beyond the classical fatigue limit. In this so-called „very high cycle fatigue“ regime (VHCF), the materials show a strong scatter in fatigue life, which makes life service ...

Technical Review of Specimens under Ultrasonic Fatigue Test

Transactions of the Korean Society of Mechanical Engineers A, 2013
An accelerated ultrasonic fatigue test(UFT) has been used for analyzing very high cycle fatigue( VHCF, > ). This study reviews how the test specimen is to be determined. We focus on UFT using a resonance of 20 kHz. The specimen geometry is determined by selecting test materials by using a dynamic Young's modulus and wavelength of 20 kHz.

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.

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.

Damping monitoring methods during ultrasonic fatigue testing: A comparative study

Review of Scientific Instruments
Ultrasonic fatigue testing is quite a useful tool for exploring the high-cycle and very-high-cycle fatigue properties of materials. Damping monitoring has been proved to be fairly effective in indicating the generated defects or damage in the testing specimen.
