FE Model of Non-Fourier Heat Conduction

This course covers the essential principles of non-Fourier heat conduction, a key concept in comprehending specific welding processes and ultrasound pulse laser processing. It delves into the distinctions between Fourier and non-Fourier heat conduction models, the assumptions made in Fourier's law, and how these assumptions are modified in non-Fourier models. The course also explains how to develop a finite element model for non-Fourier heat conduction and its application in different scenarios. For example, the course illustrates how to use the model to analyze the heating of nano films using ultrasound pulse lasers. The course further explores the concept of thermal inertia and its effects on temperature profiles during welding processes. An example of welding steel and aluminum alloy using ultrasound pulse lasers is used to illustrate these concepts. Lastly, the course covers the concept of stress analysis in ultra-soft pulse laser heating processes and the impact of thermal contact resistance in multi-layer films.
