Instructor
Dr. Valeria La Saponara Office: Bainer 2100
Email: vlasaponara@ucdavis.edu Phone: (530)-754-8938
Office hours: Mondays and Wednesdays 10:45 am-11:45 am, or by appointment.
Course web site
http://mae.ucdavis.edu/vlasaponara/mae237.html
The course web site contains syllabus, announcements, homework, solutions to homework and past
exams. Most documents will be in .pdf format.
Students are required to check their UC Davis/LLNL/Sandia email account and the course web site
throughout the quarter.
There is a mailing list, mae237-s10@ucdavis.edu, accessible only to people registered in this course.
The email is archived, and access to the archive requires UC Davis login.
Textbook
Mechanics of Fibrous Composites (Hardcover, 1997), Author: Carl T. Herakovich, ISBN: 0471106364
Additional notes will be either distributed as photocopies, or posted as .pdf files on the mailing list/course
web site.

Homework
The UC Davis Code of Academic Conduct applies to this course, http://sja.ucdavis.edu/cac.html .
1

Students are encouraged to discuss with each other about the homework, but the final product needs to be
only the work of the person who has the name on it. Copy-and-paste and plagiarism will not be
tolerated.
Late homework will not be accepted, unless there is a documented emergency, discussed with the
instructor before the deadline.
Homework in electronic form will only be accepted if sent from virus-free UC Davis or LLNL/Sandia
accounts. The size of the overall attachments must be less than 5 MB. At (electronic) submission, you
need to carbon-copy yourself.
Homework codes
Homework needs to be submitted as one single document, in Word or .pdf format. The only exception
to the one-file policy is for Excel spreadsheets, which must be e-mailed separately. Source codes must be
included in the document itself, with the exception of Excel spreadsheets, as discussed above.
Acceptable ‘languages’ are MATLAB, FORTRAN and R. Source codes must be commented and include
units for input and output.
Academic holidays
Monday May 31 st , Memorial Day
Grading, exams
The final grade for the course will be based on the following:
Homework 20%
Midterm exam on (tentative) Wednesday May 12 th , 2:10-4 pm 40%
Final exam on Monday June 7 th , 3:30-5:30 pm 40%
Total 100%
The exams will be open notes/open books. Make-up exams will only be given for documented
emergencies.

Classroom Etiquette
This section has been prepared using the material available on the web site of UC Davis Student Judicial
Affairs, www. sja.ucdavis.edu/
The following expectations are to enhance the students’ ability to learn in this class, to avoid disruptions
and distractions, and to improve the quality of the classroom experience. Repeated failure to meet these
expectations may result in a lower grade for the course. Student Judicial Affairs gives the instructor the
authority and discretion to set rules that foster student learning, and to determine what constitutes
disruptive behavior.
