Abstract
A method is proposed for assessing the degradation state o f an article during its life cycle in different periods o f operation in order to timely establish and predict the nature o f the structural changes that correspond to the boundary o f their pre-destruction and is characterized by the appearance o f zones with a coercive force below the initial level. The modeling of degradation processes associated with the development o f arising stresses and structural changes is performed.
