This is an introductory course on nonlinear finite element analysis of solid mechanics and heat transfer problems. Nonlinearities can be caused by changes in geometry or be due to nonlinear material behavior. Both types of nonlinearities are covered in this course.
Goals
This learning project aims to.
provide the mathematical foundations of the finite element formulation for engineering applications (solids, heat, fluids).
expose students to some of the recent trends and research areas in finite elements.
Here's a short quiz to help you find out what you need to brush up on before you dig into the course:
