Make-Up Exams
Make-up exams may be given to those who have valid excuses approved by the department. A single make-up exam is given at the end of the term.
Projects:
Projects will be assigned after the 5th week of the course. Project progress is monitored by the assistant every two weeks. Use of a finite element program, which will be indicated, is required.
Experiments:
Experiments to be completed are:
1. Tensile test
2. Compression test (Cooke and Larke)
3. Plane-strain compression test
4. Bending test
5. Impact test
6. Hardness test
7. Erickson test
8. Torsion test
The reports of the experiments should be submitted within two weeks after the day of the experiment. Late reports will not be accepted. The reports should have a title page format as shown in the web page.
Demonstrations:
1. Extrusion
2. Hydraulic bulging
3. Deep-drawing
