Abstract
The paper studies longitudinal strains occurring along the height of a cylindrical object as a result of the temperature difference along the cylinder radius. The authors identified mathematical relations ensuring calculations of normal, tangential, and equivalent stresses. Such procedure may be applied to determine a stress state of cylinders 0.1 and 0.05 m in radius, when heating up to 400°C. It is showed that changes in a cylinder radius, maintaining the same heating conditions, result in decreasing maximum tension stresses from 4.59 MPa to 2.39 MPa, and compressive stresses from 4.31 MPa to 2.25 MPa. The authors determined principal stresses along a cylindrical rod radius during heating.
