EGM5533: Applied Elasticity and Advanced Mechanics of Solids

Spring 2008 

5-1: Since a few of you complained about having only one formula page, keep in mind that you will need the most basic equations.

4-17: Deadline for bonus problem is 5PM EDT , Wednesday 4-30.

4-16: Homework assigned, one problem may appear in part on final exam.

4-15: Physical and understanding principles for bonus problems posted to facilitate inventing them.

3-31: Homework assigned, due 4-16.

3-28: Problem 11.1 replaced problem 11.12 in homework set. Note that it is to your advantage to submit each bonus problem as soon as you have it to reduce the chance of being scooped. You can submit later for another chapter.

3-27: Bonus problems available with up to 2% bonus per problem.

2-25: Actions taken in reaction to feedback by students.

Virtual work approaches, elastic energy principles, plastic limit theorems, creep deformation procedures, introduction to instability and fracture mechanics. Design applications. Pre-requisites: EGM 3520 (or an equivalent undergraduate course on Mechanics of Materials).

Topics:

1.      Theory of stress and strain

2.      Stress-strain-temperature relation

3.      Inelastic material behavior

4.      Energy methods

5.      Torsion of shafts

6.      Bending of beams

7.      Stability of columns

8.      Fracture mechanics

COURSE ASSESSMENT

Homework: Homework assignments help students absorb methodology and concepts taught in the course and prepare them for the exams. There is 10% bonus for homework done by a word processor or very easy-to-read handwriting with detailed explanations at the level of posted solutions. Homework cannot be submitted after a solution is posted, typically 2-3 days after it is due. Homework may be submitted with no late penalty by 5PM on the day due (put in my mailbox, email or fax me for distance students). After that, there is 10% penalty per day (distance students have two extra days, but still cannot submit after solution is posted). Homework with lowest grade will not be counted. If submitted by email, copy TA

Bonus questions: There is a bonus of 0.2 points for emailing correct answers to the question in the reading assignment up to 10 such answers. For credit it must emailed before the next lecture (or before the lecture after the next for distance students with copy to TA). The subject line should give the date the of the lecture when the question is discussed (one lecture after the question is posed). There will be an additional bonus of 0.3 points if I like the answer enough to post it as the official answer. That credit will be divided between all the students who provided that answer. Note that for some questions I will post a limit on the number of words in the answer.

Exams: In-class exams are closed book, except for one 8.5"x11" page, written in any density (student may bring a magnifier). No calculators. There are no make-up exams. Students who miss an exam because of valid medical problem or family emergency will need to take comprehensive final exam, which will count also for the missed exam. Otherwise, it is optional to answer only questions relating to last part of material in final exam. If you answer all questions in the final exam, its grade may replace the lowest grade of one of the in-term exams.

Grading Policy: 25% homework, 75% three exams. Grades are on a absolute scale (A=91+, B+=86+, B=81+, etc.). Predicted grades, based on homework and exams to date are posted during the semester beginning after the first in-term exam. Grade calculator.

Student Helpers: There are several opportunities for students to act as helpers to their classmates and earn credit. Homework helpers complete the homework and show it to the instructor on the afternoon preceding one class period before the homework is due (for example, if the homework is due on Friday, this will be Tuesday afternoon). They help detect difficulties in homework problems unforeseen by the instructor. This help is rewarded by 10% bonus on each homework. “Class Hecklers” are responsible for raising questions in class when the instructor is not clear or they suspect an error. They must not miss more than four classes and coordinate with the other hecklers to ensure that at least one of them attends any class. Full attendance for a heckler is worth 5 points added to final course average. This will be reduced by 0.125 points per missed class. Students who are interested in these positions should email the instructor explaining why they are suitable.

 Academic honesty: All students admitted to the University of Florida have signed a statement of academic honesty committing them to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a student at the University of Florida and to be honest in all work submitted and exams taken in this class and all others.

Accommodation for Students with Disabilities: Students Requesting classroom accommodation must first register with the Dean of Students Office. That office will provide the student with documentation that he/she must provide to the course instructor when requesting accommodation.

UF Counseling Services: Resources are available on-campus for students having personal problems or lacking clear career and academic goals. The resources include:

Software Use: All faculty, staff and student of the University are required and expected to obey the laws and legal agreements governing software use. Failure to do so can lead to monetary damages and/or criminal penalties for the individual violator. Because such violations are also against University policies and rules, disciplinary action will be taken as appropriate. We, the members of the University of Florida community, pledge to uphold ourselves and our peers to the highest standards of honesty and integrity.
