Journal of Thermal Stresses 42 (11)2019:1458-1479Summary: For given geometrical properties of a shrink fit, the interface pressure is decisive for reliable operation and should stay as large as possible during operation. Using an appropriate functionally graded material for the hub facilitates a less decreasing interface pressure with increasing angular speed and, moreover, substantial weight-reduction. However, temperature cycles may influence the interface pressure considerably, and if partial plastification occurs, even a permanent decrease may result. These issues are discussed by analytical means, and both homogeneous and inhomogeneous temperature fields in an initially elastic shrink fit with hollow steel inclusion and steel-aluminum FGM-hub are considered.
