MECT 4323: APPLICATIONS IN STRESS ANALYSIS


College of Technology Building T-2, Room 356

Tuesday 7 TO 10 PM

3 credit hours

PREREQUISITES: To enroll in this course, students should have taken MECT 3355 and MATH 1432 or equivalents.


COURSE DESCRIPTION


The purpose of this course is to develop students skills in stress analysis techniques and be able to apply the fundamental stress analysis tools of engineers beam theory, thick and thin cylinder theory as well as energy methods and elementary plasticity


REQUIRED MATERIALS


Boresi, A.P. and Schmidt R.J (2003). Advanced Mechanics of Materials. Sixth Edition John Wiley and Sons.


COURSE OUTCOMES AND ASSESSMENTS


By the end of the course, students will be able to:

theory to calculate load paths, deformation and internal structural load distribution.


  • Indentify basic structure types and applicable theory

  • Calculate structural load paths on the basis of mechanical properties

  • Determine structural load distribution, internal stress distribution and structural deformation.

Students will be evaluated on the basis of two course works throughout the semester and a final exam.

1. Course work 1 – Load distribution in frame structure - 10%

2. Coursework 2 – three selected problems from the syllabus – 10%


Students are expected to attend every class. There will be no make up exams unless a demonstrable emergency occurs. All exams will be performance based using a rubric that will be presented to students the week before the test.


TAC-ABET CRITERION 3 PROGRAM OUTCOMES:


This course covers program outcomes a, b, d, g, h, i, k and m.

ACADEMIC HONESTY POLICY


Students are expected to abide by the university’s academic honesty policy in all matters concerning this course.  (http://www.uh.edu/dos/hdbk/acad/achonpol.html).  In particular, plagiarism, “Representing as one’s own work the work of another without acknowledging the source,” whether intentional or unintentional, will not be tolerated.   


STUDENT ACCOMODATIONS UNDER

THE AMERICANS WITH DISABILITIES ACT


When possible, and in accordance with 504/ADA guidelines, we will attempt to provide reasonable academic accommodations to students who request and require them. Please call the Center for Students with Disabilities at ext 3-5400 for more assistance.


Additional information on UH Student Policies


As a student of the University of Houston, the following information will be critical to you in insuring that your academic pursuits meet with success and that you encounter the fewest financial and academic difficulties possible. Please take a few moments to review the information located at:

DISCLAIMER


While every effort is made to ensure that all information and dates are accurate at the time of printing this syllabus, I reserve the right to make any changes to this course. Modifications include, but are not limited to, adding quizzes, changing assignments and/or due dates, or providing opportunities for extra credit. Verbal notification at any regularly scheduled class meeting, or through any of the established means of communication such as email, WebCT, or update of online syllabus will constitute sufficient notice. Students are responsible for keeping up to date of any changes. The current record syllabus will be maintained on WebCT.


CLASS ETIQUETTE


All students are expected to respect each others workspace and property.


HOLD HARMLESS POLICY

The University of Houston administration and faculty agree that students will be held harmless for absences due to University sanctioned activities in so far as possible. All parties recognize that not all classes are amenable to alternative assignments and in some cases it is impossible to reschedule critical learning experiences. Though faculty has the final decision regarding the appropriateness of alternative assignments or experiences, in all cases they will make a good faith effort to accommodate.


Students should work with their advisors and potential faculty members to design student course schedules that minimize absences in those courses with learning experiences that present special challenges for replication at an alternative time.

Wherever possible, all student work should be completed before the end of the course block. If it is not possible for a faculty member to replicate a learning experience that produces similar critical learning outcomes to the missed experiences in a particular course within the same block, incompletes may need to be issued to the student until such time as suitable learning experiences, if possible, can occur. Final decisions regarding the appropriateness of assigning incomplete grades are made exclusively by the faculty.


This policy is effective so long as:


1. The student provides both verbal and written communication to the faculty member or employer on Day 1 of any given block.


2. The student is engaged in a university-sanctioned event necessitating the student’s absence. Examples of such events include (but are not limited to) athletic activities, career fairs, and field experiences. The faculty member or employer must be able to verify this activity if so desired.

The student is not excused from academic work required for a course, but in these instances will be allowed to work with a faculty member or employer to alter deadlines, or complete alternate assignments, or make up work as assigned by the faculty member or employer in so far as possible.

Students will not be penalized for engaging in such activity and the faculty member or employer shall attempt to accommodate the student as long as the student provides for 1 and 2 above.
