<p>This thesis is intended to be a ground for the implementing of solid mechanics calculations of an expander axle in an existing CAD programme. The main parameters to be calculated are: effective stress, stress components in axial and radial direction, shear stress as well as maximum force and fatigue analysis. In order to achieve the above mentioned goal, calculations were made by hand. At the end of any of the chapters, a diagram on the input/output data and the equations needed for performing the calculations was drawn.</p>
