Abstract

Residual deformations and stresses after shrinkage fit of a hollow cylinder with an internal stator are calculated. The numerical simulations are performed using the thermal-elastic-plastic finite element method. Two idealized models for the shrinkage fitted structure are investigated. In these models the 3-D solid elements with local coordinate system are used. In order to prevent the numerical locking phenomena, the reduced integration method is introduced and its effectiveness is discussed. The calculated radial shrinkages are compared with the measured values obtained by experiment. The results show that good agreement can be obtained if the reduced integration method is applied to the cylinders.
