Finite element modeling of welding processes

The welding process involves complex interaction of several mechanisms. The fundamental understanding relied on basic mechanisms such as heat transfer and/or fluid flow, and associated distortion and residual stress generation including the effect of metallurgical transformation for a welding process is the focus of this course. It helps to develop the numerical model, and makes the foundation for analysis and experimentation for the process. The development of computational models for welding process relies on mathematical expression of the governing mechanism. It helps to design relevant experiments and drives to find the data to be obtained. Mutual understanding between numerical and experimental results leads to better insight of the welding processes that impact on the improvement of existing process and directs to the development of new process. This course emphasized on the development of finite element based numerical model of both fusion and solid state welding processes. The development of FE-based model is presented in a simplified way to understand the subject at elementary level. The broad impact is that the students will be able to develop FE-based heat transfer, fluid flow and stress analysis model of welding process using standard commercial package. However, this course does not intend to cover the learning of the commercial software.
