Course Objectives:

 

The objective of the course is to develop an understanding of the underlying mathematical theory behind the finite element method and its application to the solution of problems from solid mechanics. The course involves homework assignments, a midterm, and a term project. The term project will involve the application of the finite element method to a realistic and sufficiently complex engineering problem that is selected by the student and approved by the instructor. Such projects typically require the use of a commercial finite element code. Codes available to the students in the Mechanical & Industrial Engineering Computer Laboratory (MICL) at the University of Massachusetts include ANSYS 5.7, Pro Mechanica, and FIDAP.

 

After completing the course, the student will have an in-depth understanding of the basic theory of the finite element method, as well as some hands-on experience in solving complex engineering problems by the finite element method.

Homework problems will be assigned periodically during the semester. Homework problems may require use of PC-based software tools, such as spreadsheets and symbolic math tools (i.e. MATHCAD, Mathematica, etc.) for calculations, or in the case of modeling exercises they may required the use of commercial finite element codes, such as ANSYS or Pro Mechanica. You may consult your peers, but you must do your own work and pledge it with the following signed statement: this assignment is my own work. Late or unpledged homework and project will not be accepted.
