Topics to be covered in this course
The following topics to be covered in this course:
- Basic Equation of linear elasticity
- Constitutive behavior of materials
- Linear elasticity solutions
- Engineering structural analysis
- Euler-Bernoulli beam theory
- Three-dimensional beam theory
- Thin-walled beams
The lectures will cover the theoretical foundations of structural analysis, and the syllabus will be followed as closely as possible. Because of time limitations, some material may be covered quickly; you are expected to ask questions for clarification. If you do not ask questions, I will conclude that you understand the material. You class attendance is mandatory. Do not expect to get by without a lot of work.
- Arrive class on time.
- Tablets and laptops are allowed for taking notes only.
- No eating
- No sleeping
- No excessive talking
- No texting
- No reading of newspapers, magazines, or Internet articles
- No puzzles or games
The overall numerical grade for this course will be computed using the weighting factors shown in Table 1.
You will fail the course if your grade in any of the quizzes is below %60 of the total grade of that quiz.
|Attendance, Participation, Homework||%10|
Table 1: Grade weighting factors
Table 2 explains about grade scales.
|A||95 or above||B||83 – 86||C||70 – 76|
|A-||90 – 94||B-||80 – 82||D||60 – 69|
|B+||87 – 89||C+||77 – 79||F||59 or less|
Table 2: Grade scales
Students registered in EAS 5221 require submitting a term paper. The instructor must approve the subject and the approach. The grade for the term paper counts as one additional exam.
Homework will be assigned on a weekly basis. Homework is assigned on Thursday lectures and is due the next Thursday, in class. Homework is a vital part of the learning process, and makes up to 10% of your final grade. To make sure no homework is forgotten, an aging factor will be built into the grading as shown in Table 3. Do not forget to use the mandatory homework format, see section 7.
|Date homework is turned in||Aging factor|
|On the due date||actual grade|
|Up to the Monday after due date||actual grade – 1/10|
|Up to the Wednesday after due date||actual grade – 2/10|
|Never turned in||0/10|

Quizzes and Final
Quizzes will be held at the dates announced a week before. Quizzes are closed book and closed notes, but open minds. Three crib sheets, hand written front and back, are allowed at each quiz.
The comprehensive final exam will be held on week of finals. The format of the final is identical to that of the quizzes, but five crib sheets are allowed.
The following reference textbook will be followed in this course: Structural Analysis: With Applications to Aerospace Structures, O.A. Bauchau and J.I. Craig, Springer

Mandatory Homework Format
The homework you turn in are a good measure of the quality of your work and the effort you put into a course. Make every effort to present your work in the best possible manner.
- Use engineering paper only. PRINTyour name clearly on the TOP RIGHT-HANDcorner of each and every page. Work only on one side of the sheets. STAPLEall sheets together.
- Be careful about neatness and being organized.
- Neatness counts, it is a sound approach to engineering.
- Clearly indicate your final results by putting a box around your answers.
- Do not forget to keep track of UNITSduring your calculations.
- It is a convenient way to uncover math errors.
- Please indicate units for your final answers: a final answer without units is not an answer.
- Describe your solution process first:
- Provide a sketch of the problem with all relevant information.
- If applicable, draw a free body diagram.
- Derive the equations of the problem.
- Discuss your approach to solving them (analytical, numerical, etc.)
- Provide expressions for all the results you are plotting.
- Comment on the physical nature and significance of your answers.
- Please do not give an answer that makes no sense! It clearly indicates you do not understand the material.
- A plot conveys abstract information in a graphical manner. A plot must be drawn with the help of a software package (Matlab, Maple, etc.). Freehand drawing is a sketch, not a plot. Consider the plot shown in Fig. 1.
- Both x and y axes must be properly labeled; provide UNITS. If it is a non- dimensional quantity you are plotting, say so.
- If more than one curve appears on the plot, make sure to clearly differentiate them. Use different line styles or symbols.
- Provide a caption that explains what quantities are plotted along the x and y axes. If more than one curve appears on the plot, provide a legendto explain the meaning of each curve.
- If you are using a software package (Matlab, Maple, etc.) as a part of your solution process, include the input/output files to these packages as part of your submission.

Statement of Academic Honesty
The honor system is assumed.
- You may, and are encouraged to discuss how to work out the problem sets with your classmates. Classmates are an excellent source of information. There is an obvious difference between a constructive discussion about a homework with a friend, and copying your friend’s homework.
- Of course, copying is not permitted.
- For more information see the FIU Academic Honor Code.
