**Introduction:**

The combined stress distribution in a shrink fit composite cylinder is made up of stress distribution in the inner and outer cylinders.

**Description:**

The radial displacement of the contact surface of the inner cylinder is given by

The total interference δ at the contact is therefore given by

This gives the contact pressure in terms of the known variables as follows:

The combined stress distribution in a shrink fit composite cylinder is made up of stress distribution in the inner and outer cylinders and this is shown in figure below

Residual circumferential stress is maximum at r = ri for the inner cylinder and is given by

Residual circumferential stress is maximum at r = rs for the outer cylinder and is given by

Stresses due to fluid pressure must be superimposed on this to find the complete stress distribution.
