Full-Scale Fatigue Testing of Compressor Cylinders

Journal of Fluids Engineering, 1953
Abstract Present needs for higher-pressure compressor cylinders for natural-gas pipe lines introduce complexities of design and manufacture. Through full-scale fatigue testing, designs incorporating high-strength cast irons are proved suitable at considerable saving to the user. Comparison of the fatigue-test failure of the design to the

Full-Scale Fatigue Testing

2016
Full-scale fatigue testing (FSFT) forms an integral part of the aircraft development and certification prior to induction into service. The five historical stages of evolution of FSFT are described with a detailed description of present-day requirements including composite structures. The technology used in the FSFT process is explained in detail.

Full-Scale Fatigue Testing With 130K Yield Tubing

SPE/ICoTA Coiled Tubing & Well Intervention Conference and Exhibition, 2012
Abstract Coiled tubing (CT) is widely used in the well-intervention business as a practical and cost-effective means of servicing wells. Since CT’s inception, the use of continuous steel tubular has been the primary means of conduit for the applications required.

Full Scale Wing Fatigue Testing

1957
The problem of fatigue in aircraft structures has been under investigation for many years. Much work has been accomplished in testing and evaluating the effects of different cyclic loads primarily upon material coupons, typical joints, and small component parts.

Full Scale Sour Fatigue Testing With Dense Phase Gases

Volume 6: Materials Technology; Polar and Arctic Sciences and Technology; Petroleum Technology Symposium, 2012
The petrochemical industry is very interested in the sour service fatigue performance of girth welded steel pipes. As a result several papers are published every year addressing this issue, and several Joint Industry Projects (JIP) are currently underway addressing different aspects of sour service performance of steel pipelines.

Shift Factors for Asphalt Fatigue from Full-Scale Testing

Transportation Research Record: Journal of the Transportation Research Board, 2011
Asphalt fatigue lives determined in the laboratory must be shifted to predict the performance of in-service pavements. Determination of the shift factor to be applied constitutes one of the main challenges of flexible pavements design. Experimental data from four sections tested for 28 months at the CEDEX test track provided detailed information ...

Full Scale Fatigue Testing for Mitsubishi Regional Jet

2019
Mitsubishi Aircraft Corporation is performing the full-scale fatigue testing (FSFT) for Mitsubishi Reginal Jet (MRJ) type certification. Main objective of this test is to show freedom from wide spread fatigue damage (WFD) during the life of aircraft and establish Limit of Validity (LOV).
