ABSTRACT

Analysis of tubular elements takes a special place in design of rotating shell constructions. Taking into account that a considerable part of constructions is subjected to corrosion, analysis of rotating corroded pipes is of great practical interest. Action of aggressive medium on construction may bring to various changes, particularly, to change of geometrical parameters. Definition of these changes is an important factor for determining changes of strain-stress state of construction in the corrosion process. Corrosive wear may depend on deformation of points of surface of construction-medium contact. On the other hand, deformation of points depends on geometrical parameters of the construction. Thus, definition of change of geometrical parameters is reduced to solution of nonseparable equations of motion of points and equations of corrosive wear.
