Mechanical Engineering 563
- Theory of Elasticity
Fall Quarter 1997 / 8:00 - 9:15 MWF
/ BH 322
PRIMARY GOAL: To acquaint
students with the basic theory of elasticity and how it is applied to engineering
problems.

TEXTBOOK:
Advanced Strength and Applied Elasticity, Third Edition,
Ansel Ugural and Saul Fenster, Prentice Hall, New Jersey, 1995, ISBN: 0-13-137589-X
FINITE ELEMENT CODE:
The FRANC2D/L finite element code will be used extensively
in this course. This program can be downloaded free of charge by clicking

GRADING:
Homework 15%
Computer Project 15%
Strain Gage Project and Presentation 20%
Exam 1 20%
Exam 2 (Comprehensive) 30%
GRADING SCALE:
A 90 - 100% (highest degree of excellence)
B 80 - 89% (superior)
C 70 - 79% (average)
D 60 - 69% (minimum quality of work to receive course credit)
F < 60% (failure)
Note: The lower limit in each grade range may be lowered slightly
such that the division between letter grades occur at any large gaps in
the grade spectrum. This adjustment will be determined only after the final
averages are computed and may or may not alter the grade scale.
HOMEWORK:
-
At least one homework assignment will be given per week.
-
Homework assignments are due at the beginning of the class
period after which they are assigned (unless otherwise noted). Since homework
solutions are given, late homework WILL NOT
be accepted.
-
Discussion of homework problems among students is encouraged.
However, any exchange of written information regarding the homework problems
is considered cheating. Copying homework solutions from solution manuals
or from previous quarters is also considered cheating. In accordance
with Louisiana Tech University policy, this may include expulsion from
the course with a grade of "F".
-
Homework must be neat and legible. For each problem, provide
pertinent information to define the problem, list quantities to be found,
and provide a solution that is easy to follow. All intermediate steps must
be clearly shown; answers should be clearly marked and must include appropriate
units. Look HERE for what
the grader is looking for.
-
Complete homework using engineering paper or white printer
paper. The use of Mathcad and TKSolver is strongly encouraged. However,
make sure that you annotate your computer output so that it conforms to
the homework structure given above.
-
At least two problems of each homework assignment will be
graded (at least 18 homework problems will be graded this quarter).
COMPUTER PROJECT:
-
One computer project will be assigned .
-
The project must be submitted as a report. Check HERE
for the required report format.
-
All work on the projects MUST
be completed individually (no sharing of information,
either verbal or written, is allowed). In accordance with
Louisiana Tech University policy, this may include expulsion from the course
with a grade of "F".
-
Late projects will be penalized ten percent per day, excluding
Saturday and Sunday (4 days late means that the maximum possible score
is 60%). Projects turned in on the due date AFTER the beginning
of class will be considered one day late.
STRAIN GAGE PROJECT:
-
One laboratory type project will be assigned which requires
that strain gages be applied by the student. Strain gage readings
will be taken during one or more loading cycles and recorded using a data
acquisition system.
-
The project must be submitted as a report. Check HERE
for the required report format.
-
This will be a group project (2 people in each group).
-
The project must also be submitted as an oral report.
EXAMS and POP QUIZZES:
-
One side of a 8 1/2 x 11 inch formula sheet may be used during
exams. Only formulas and constants are allowed on this sheet. Absolutely
no text is allowed on the formula sheet (i.e., you can't even define the
variables to the formulas). Example problems may NOT be worked out on the
formula sheet. Your formula sheet is to be turned in with your exam.
-
Pop quizzes will be given at various times throughout the
quarter. Pop quizzes usually cover something that was discussed in the
previous lecture. The purpose of these unannounced pop quizzes is to encourage
attendance.
ATTENDANCE:
-
Regular and punctual class attendance is expected (refer
to page 24 of the 1997-1998 bulletin regarding attendance).
-
An unexcused absence for a pop quiz or examination will result
in a zero grade for that test.
