Calculation of layered rotating disks with account interface

The problem of calculation of layered rotating disks with the account interface is formulated. The method of the numerical decision of such problem is developed. Concrete calculations of disks on approached (not taking into account interface) and exact to theories are lead. Relative thickness of disks at which it is possible to neglect interface are determined. Influence of heavy-shrink fitting of a disk on a shaft with tightness on increase in speed of rotation is investigated. Are resulted stress diagram, describing interface.
