Grading Policy Grades will be based on homework assignments and exams as follows:

Homework assignments	25%
Midterm exam 1	35%
Final exam (comprehensive)	40%

¹ No make up exams will be given. Percentage of missed midterm exam grade will be added to the Final exam percentage.

Homework Assignments and Due dates

Homework assignments will be posted below. Note the due date and time. Late submissions will not be graded. Submit HW electronically as pdf file to the course section of Canvas. You must follow HW submission guidelines. Failure to do so will result in HW not being graded!

 

 MCAE laboratory and FE software

• To demonstrate the concepts, as well as solving homework problems, ABAQUS/CAE software is available in MCAE laboratory (room 420 EB) and EB 325 for your use.  A free student version of ABAQUS (limited to 1000 nodes) is also available for download from MCECS Computer Action Team (CAT) web site. Alternatively, you could use any software of your choice as long as it allows you to complete the assignments. Be aware, however, that I cannot answer any questions regarding other FE software syntax, or commands.

Notice to ABAQUS users

Please remember to direct all your questions regarding ABAQUS and MCAE lab ( room 420 EB) software/hardware issues to your instructor. Questions regarding networking, e-mail, printing and web access should be brought to the attention of the college computer support staff (support@cecs.pdx.edu)

Notice to Graduate Students

Graduate students who register for ME 555 may be required to complete extra work (project), usually during the last two weeks of the term. Details will be announced, and posted on the web page.

Homework Submission guidelines:

1)      Entire homework set must be submitted as one (single) PDF file

2)      Only PDF format will be accepted and graded. Other formats (including JPEG images) will be ignored and will not be graded.

3)      Use the following naming convention for homework:

 Last-name_First-name_HWxx   (where xx indicates the set number).    For example: Smith_Jane_hw2.PDF

4) If you revise your submission send a message from Canvas alerting the grader about the changes.
