The kinetics of damage accumulation in a D16ch sheet aluminum alloy (Al–Cu–Mg system) at various stages of static loading is investigated using a combined technique, which includes the detection of acoustic emission (AE) signals, structural studies, and the determination of electrical resistance and an eddy-current parameter. The dependences of these characteristics on the relative strain demonstrate the presence of four stages of specimen fracture. Correlation exponential dependences of the electrical resistance and the eddy-current parameter on damage are obtained, and they can be used to diagnose the state of the material.
