Thermal Stress Distribution in Rectangular Sheet due to Symmetric and Asymmetric Temperature Fields — Lesson 3

This lesson covers the determination of thermal stress distribution in various components subjected to high temperatures, such as power plants, process equipment, and internal combustion engines. It explains the importance of calculating not only the stresses due to mechanical load but also those arising from temperature distribution. The lesson further delves into the stress-strain relationship involving both mechanical and thermal loading. It provides a detailed explanation of how to calculate thermal stress distribution when a temperature distribution is given in the body. The lesson also includes practical examples and illustrations to help understand the concept better.
