Application of FEM to Model Welding Processes Part I

This course covers the comprehensive understanding of the Finite Element Method (FEM) and its application in modeling welding processes. It starts with the basics of FEM, demonstrating how it forms linear systems of equations that aid in comprehending the distribution of variables like temperature and distortion in welding processes. The course further delves into the development of models for various welding processes, explaining the governing equations and boundary conditions. It also explores the use of FEM in solving heat conduction equations and modeling welding processes such as fusion welding, resistance bottling, and solid-state dwelling. Additionally, the course discusses the material flow model in fusion rolling processes, the effects of metal flow, and the importance of surface flux. It concludes with the application of the penalty finite element method and tracking of the solid-liquid interface.
