An engineering method for residual life calculations for cracked MS was proposed. The applicability of the electrical conductivity parameter to monitor the aluminium alloys structure change was analyzed and the design principle of the eddy current structuroscope was given. The results of skin material degradation in airplane ("Antonov" type) by developed structuroscope are considered Product Description popup.authors popup.nrat_date 2020-04-02 Close
