Description

This course introduces the basics and methodologies of finite element analysis of heat transfer, thermal and residual stresses in casting, heat treating, and welding of metals and alloys. Tutorials and examples will be provided for exercises. Each student will identify one subject of interest as his/her course project and solve the problem. Students are expected to develop in-depth knowledge of the thermal and mechanical aspects of one process and to gain basic understanding of other processes.

Objectives

• To understand the thermal and mechanical behavior of metals and alloys during thermal processing
• To simulate the thermal and mechanical changes in metals and alloys in thermal processing using finite element analysis tools
