Non-Destructive Testing of Aerospace Structures: Granularity and Data Mining Approach
نویسندگان
چکیده
| For large aerospace structures, it is extremely important to detect faults, and non-destructive testing is the only practical way to do it. Based on measurements of ultrasonic waves, Eddy currents, magnetic resonance, etc., we reconstruct the locations of the faults. The best (most eecient) known statistical methods for fault reconstruction are not perfect. We show that the use of expert knowledge-based granulation improves the quality of fault reconstruction.

Development of a Design Procedure for Aeronautical Structures Based on Reliability
In this paper, an approach to aeronautical structural design based on reliability analysis is presented. In this way, the concept of level of safety is discussed and methods of its calculation using statistical data are described. Based on the concept of level of safety, a design procedure is proposed. In order to validate this design procedure, two design cases are studied. In the first case s...
متن کاملInterval Methods in Non-Destructive Testing of Aerospace Structures and in Mammography
Flight is a very stressful experience for materials and structures. As a result, even small faults in aerospace structures can lead to catastrophic results. It is therefore desirable to test the structural integrity of an airplane and/or a space structure before the ight (and ideally, in-ight as well) and detect potential faults. In this paper, we show that interval methods can help.
متن کاملMeasurement and Modelling of the Rubber Resilience based on Ultrasonic Non-destructive Testing in Tires
In tire industry, it is very crucial to evaluate physical and mechanical properties of the rubber which is used for production of the tire, to ensure the quality of the final product. Resilience is an important property of a rubber, which cannot be evaluated through direct measurement in production cycle in this industry. Therefore, non-destructive ultrasonic testing, which has been used in man...
