Introduction to Finite Elements

Description: Understand and apply finite element methods to mechanical engineering problems. Develop working knowledge on how to formulate finite element solutions using direct stiffness and weighted residual methods (including least-square, collocation and Galerkin’s formulations) to problems in structural mechanics and heat transfer. Solve 1-D and 2-D FEM solution with hand-calculation and MATLAB™. Practical use of commercial finite element analysis software COSMOS™ is also introduced. (fall)


Who takes it: Junior/senior mechanical engineering students interested in the topic, satisfies mechanical engineering elective requirement. (elective).

Pre-requisite: MATH 233 Linear Algebra, MATH 234 Differential Equation (used extensively).

Course objective: Student understand the mathematical foundation of finite element analysis; doing hand-calculation in 1-D; properly operate commercial FEA analysis package, understand its limitation.

Textbook: Introduction to the Finite Element Method: Theory, Programming and Application, by Erik Thompson, 1st Edition (2004), ISBN: 0471267538

I do not teach this course at the moment, so do not purchase the book in advance (also, this book is terse and the students hated it with a vangence). Recommended self-study book for junior/seniors: A First Course in Finite Element Method, by Daryl L. Logan, 3rd Edition (2000), ISBN: 0-534-38517-6. For better theoretical treatment for undergrad, I like Introduction to the Finite Element Method by Ottosen and Petersson, Prentice Hall; (1992); ISBN: 0134738772. It is out of print, but you can find it in bookseller websites or on Ebay.
