Accelerating Full Scale Fatigue Testing

Proceedings of the Vertical Flight Society 79th Annual Forum, 2023
This paper will discuss the use of Model Predictive Control (MPC) to increase the speed and accuracy of airframe fatigue testing. This will save time and cost while providing a very high fidelity test that will greatly reduce future fleet problems.

Fatigue Test on a Full Scale Panel

Key Engineering Materials, 2006
Fatigue test on a full scale panel with complex loading and geometry has been carried out by using a tri-axial test machine located in the laboratory of the University of Naples. The aeronautical test panel was designed and manufactured by Alenia. The demonstrator is made up of two parts which are linked by a transversal joint that is parallel to the ...

Full-Scale Fatigue Test on X60 Spiral Linepipe

Volume 4: Terry Jones Pipeline Technology; Ocean Space Utilization; CFD and VIV Symposium, 2006
Both fluctuation of operation pressure and transmission halt have obvious effect on the lifetime of the pipeline. When there exist flaws in the pipes, cyclic load caused by pressure fluctuation will promote the development of such defects especially as cracks. A full-scale fatigue test was performed on the X60 Spiral Submerged Arc-Welded pipes (Outside

Full-Scale Fatigue Testing of TLP Tendons

Offshore Technology Conference, 1991
ABSTRACT The design of TLP tendons and tendon connectors to resist fatigue failures requires consideration of many factors, such as mean and alternating stresses, cycles, welding, residual stresses, base metal fatigue, and weld profile control. Many assumptions are necessary to do this.

Computer-based full scale fatigue testing

International Journal of Fatigue, 1979
Abstract Computer-based methods can help to ease the difficulties of realistic full-scale testing by unravelling some of the complexities of multi-channel service loading simulation during the stages of data acquisition, data analysis and test rig control.

A full-scale structural fatigue test program

Journal of Aircraft, 1964
Test methods are described for an experimental fatigue evaluation of a full-scale airplane structure. Specific reference is made to a fatigue test program conducted on the Lockheed P3A wing and gear. A flight-by-flight test loading spectrum comprising 7500 flight hours was constructed to represent the total service experience of the airplane.

Fatigue load testing of full-scale dynamic message signs

Engineering Structures, 2021
Abstract This paper summarizes results acquired from the fatigue testings of two full-scale dynamic message signs (DMSs) fabricated by a local manufacturer in the United States. One DMS with adhesive joints and one DMS with welded joints were tested with fatigue loading.
