Course Description:
This course aims at introducing and discussing the fundamentals of finite element analysis (FEA). Formulation of the finite element method (FEM) using variational and weighted residual methods will be discussed. Details of several element types and interpolation functions will be covered. Application to solve implicit problems such as in elasticity, thermal conduction, and other problems of engineering and physics will be used to enforce the principles of FEM. The course uses the finite element code
HyperWorks/OptiStruct for the applications and problems, examples of various types will be given as homework.

Grading Criteria:
Grades will be calculated accounting for a) homework assignments, b) the midterm exam and c) the final exam. Each will contribute to the final grade as it follows:
Homework 15%
Midterm 35%
Final 50%
Grades will be curved if necessary.
For the remote EDGE students, the midterm exam will be posted on the class website at the time of the exam, to be downloaded and returned by the student via electronic means
(fax, or scan+email). Please be sure you will have access to the internet at that time.
