Credit Hours:

Learning Objective:

Understand complicated 3-D state of stress for both determinate and indeterminate problems. Learn advance theory of elasticity. Gain fundamental knowledge of bodies in contact. Learn solution methods for torsion of prismatic section and bending of asymmetric cross section. Apply energy method to solve problems for linear and nonlinear materials.

Description:

Topics Covered:

Stress analysis, index notation, static and dynamic failure theories, two dimensional problems in elasticity, contact stress, fracture, introduction to finite difference and element methods, bending of non-symmetrical sections, curved beam theory, torsion of prismatic section, and energy methods.

Prerequisites:

Undergraduate courses in machine design and mechanics of materials or consent of instructor. Some basic knowledge of computer programming and finite element software.

Applied / Theory:

50 / 50

Web Address:

Blackboard

Web Content:

Course website under modification. Will contain: schedule, syllabus, lecture notes, homework sets, project info., grades.

Homework:

Weekly assignments. Blackboard will be used to provide course information (i.e. hw, announcements, etc.)

Projects:

The project is an assigned or proposed individual work relevant to the course objective. You will need to conduct a literature search in the library on the subject matter. You will need to develop computer software or use available software (i.e. ABAQUS, ANSYS, Algor, etc.) to complete the project assignment. You are required to provide a typed, well-written document on your findings and give a presentation of your findings.
You are also required to read and develop a three page single space essay on a scientist of your choice. The essay need to describe his life and work.

Exams:

Two or three in class exams and one final exam.

Textbooks:

Official textbook information is now listed in the Schedule of Classes. NOTE: Textbook information is subject to be changed at any time at the discretion of the faculty member. If you have questions or concerns please contact the academic department.

Computer Requirements:

ProEd minimum computer requirements; access to FEA software (i.e., ABAQUS, ANSYS, etc.), MATLAB, and Maple (http://www.maplesoft.com/). The student version of Matlab is reasonably priced. Details can be found at the website of The Mathworks, Inc. (http://www.mathworks.com/products/education/student_version/sc/index.shtml). Many programs and apps are available remotely. Some, like MATLAB, and SAS are through Purdue GoRemote (http://goremote.ics.purdue.edu). Others you may need to purchase and the instructor will provide this information (students who do not have access to any FEA Code/Software need to buy a copy of ANSYS/ED on CD). Information on access is usually provided during the first week of the semester, in initial handouts provided prior to the beginning of the semester, on the course website, etc. Homework assignments and solution to the exams and homeworks, announcements and clarification will be posted on the course Web site.
