Thermal Stresses:
Thermal stresses are the stresses induced in a body due to change in temperature. Thermal stresses are setup in a body when the temperatures of the body is raised or lowered and the body is not allowed to expand or contract freely.
This unit introduces you to the effect of temperature on materials and completely or partially restrained bodies. This introduces the concept of thermal stresses & the method to find out them in simple and compound bars.
Objectives
After studying this unit, you should be able to
- describe the effect of temperature on bodies,
- understand how thermal stresses are produced in materials, and
- Find out thermal stresses in stepped, uniform, tapered and compound bars.
