Automated diagnostics of damage of aluminum alloy under conditions of high-cycle fatigue

Abstract

The analysis of loading conditions of modern civil aircrafts, the existing methods for evaluation of the accumulated fatigue damage, peculiarities of fatigue damage of aviation structural materials, results of previous fatigue investigations allowed formulating the approach to solving the problem of the quantitative evaluation of the accumulated fatigue damage of the aircraft structural elements. Cyclic loading forms the deformation relief on the surface of structural aluminum alloys, the intensity of which indicates the level of the accumulated fatigue damage.
