Abstract:

A study is conducted on the crack inspection probability by using an eddy current under different thickness cover layers. Through a lot of tests, a series of data about crack inspection probability are obtained by using the eddy current under different thickness cover layers. These results can be used as a guide to the inspection for similar structures, and also as an important reference for damage tolerance design and reliablity design.

Key words: nondestructive inspection, inspection probability, statistical analysis
