Use a multistep model with step dependent contact control and step dependent loads and supports. The shaft and disk with a hole are in the model.  The shaft must have a plasticity material model.

Step 1.  Frictional contact between shaft and hole are turned off. A constraint supports the disk. A temperature load causes the disk and hole to expand.  A force is applied to bend the shaft.

Step 2. The bending force reverses to straighten the shaft.

Step 3. The force is ramped to zero.

Step 4. Frictional contact between the disk and shaft becomes active.

Step 5. Temperature load on disk returns to room temperature, disk shrink fits to shaft.

Step 6. Support for disk is disabled.
