Nonlinear finite elements
Welcome to this learning project about nonlinear finite elements!
IntroductionEdit
Finite element analysis (FEA) is a computer simulation technique used in engineering analysis. It uses a numerical technique called the finite element method (FEM) to solve partial differential equations. There are many finite element software packages, both free and proprietary. Development of the finite element method in structural mechanics is usually based on an energy principle such as the virtual work principle or the minimum total potential energy principle. *

Content summaryEdit
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.
GoalsEdit
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:
