Thermal Stresses:

Thermal stresses are the stresses induced within a body because of change in temperature. Thermal stresses are setup in a body while the temperatures of the body is increased or lowered and the body is not permitted to expand or contract freely.

Here introduces you to the effect of temperature on materials and completely or partially restrained bodies. It introduces the concept of thermal stresses and the techniques to determine them in easy and compound bars.

Objectives

After studying this Thermal stresses, you should be able to

• elaborates the effect of temperature on bodies,
• know how thermal stresses are established in materials, and
• denote thermal stresses in uniform, stepped, tapered and compound bars.
