  1. MECH3300 Finite Element Method and Fracture/Fatigue

  2. Objectives

  3. Teaching Schedule

  4. Course Web Page for Dr Daniel’s part. The notes for Dr Daniel’s part of the course are on the course web page at www.mech.uq.edu.au/courses/mech3300, in the form of Powerpoint slides. Older *.htm lecture notes that are more suited to reading than presentation in a lecture have been left there as well. You may wish to read these. The content is a little different. The full set of Powerpoint notes (4 slides per page giving 50 pages) are available from the Union Copy Shop. Obtain these and please read each lecture before I give it. The lectures will discuss these notes and elaborate on them. Demonstrations with finite element software will also be a regular part of the lectures. The web page also has quiz questions on the finite element part of the course, similar to the multiple choice questions that will be used in the exam. External links on the course web page gives the web pages of some suppliers of finite element software.

  5. Computer tutorials • You will be rostered to attend six 2 hour tutorials in 78-336 where tutorial assistance will be available on the 3 computer assignments on finite elements. (One tutorial every 2nd week and 2 for each assignment). You can work unsupervised on the assignments at other times. • Don’t underestimate the workload. Obtaining answers from the computer is the easy part. A lot of effort goes into critically interpreting the results and reporting them. • The first assignment is done with STRAND7. The assignment has been set so that it is possible to do it with the demonstration version of this package. You can download this program at home if you wish (from www.strand7.aust.com).

  6. Assessment

  7. References on energy methods This is material omitted from most introductory books on mechanics of materials. The 2nd year design text, Juvinall and Marshek, Fundamentals of Machine Component Design, discusses energy methods in sections 5.8 and 5.9. The examples provided are well worth studying. Another reference is Boresi, A. P. et al, Advanced Mechanics of Materials, Wiley, 1993.

  8. Books on finite elements • Many books focus on the mathematics of how the stiffness of a finite element is obtained. This will be only outlined in this course, which focuses more on what a user of commercial software needs to know. • Recommended text for finite elements is • G.R. Liu and S.S. Quek, The finite element method - a practical course, Butterworth/Heinemann, 2003. • This gives more of a programmers viewpoint of the subject than I will. It uses the ABAQUS package to provide examples - but describes “primitive” data preparation without a graphical interface. • A good reference text is Cook, R.D., Finite element Modelling for Stress Analysis, John Wiley and Sons, 1995, TA347.F55C665 (3 copies in library).

  9. Other books on finite elements • There are a number of scholarly, definitive texts that I consult. • On dynamics: Hughes, T.J.R., The Finite Element Method, Linear Static and Dynamic Finite Element Analysis, 1987, TA347.F5.H84. • On nonlinear analysis: Belytschko, T. , Liu, W.K and Moran, B., Nonlinear finite elements for continua and structures, 2000, Wiley. • On the full range on possible analyses: Zienkiewicz, O.C. and Taylor, R.L., The finite element method (4 volumes), Butterworth/Heinmann, 5th edition, 2000.
