The reliability of detecting cracks during nondestructive testing of aircraft components

The reliability of detecting flaws taking their dimensions into account in the applied nondestructive testing method is evaluated on the basis of the use of two probabilistic characteristics, viz., the probability of detecting cracks of different lengths (which are usually preset) and the distributi...

Zusammenfassung:	The reliability of detecting flaws taking their dimensions into account in the applied nondestructive testing method is evaluated on the basis of the use of two probabilistic characteristics, viz., the probability of detecting cracks of different lengths (which are usually preset) and the distribution of the lengths of the cracks that are present in a structure. A method is proposed for evaluating the a priori distribution of the lengths of cracks in a structure using the results of the performed testing.
