ESB-E Lab: MW 10:00 – 10:50 AM Room G78 ESB-E Text: None References: Introduction to Finite Element Analysis and Design, N. Kim and B. Sankar, Wiley, 2009 Pre-requisites: MAE342 (or MAE245) and MAE 343 Course Objectives: The objective of this course is to provide students with the necessary knowledge of the computer aided design (CAD) and finite element analysis (FEA). The course will provide students with the methods needed to formulate analytical and numerical solutions to heat transfer problems. Applications will be presented and discussed. Goals1 of an undergraduate heat transfer course are to: A. The capability to identify and formulate a computational design analysis using finite element stiffness matrices to determine structural response to static and dynamic loads under a prescribed boundary condition. (ABET Outcome E) B. The capability of using commercial FEM software to design and analyze mechanical, structural systems. (ABET Outcome C and K) C. The capability of solving relatively complex engineering problems by identifying a problem, formulating a solution and solving the problem through the use of finite element analysis. (ABET Outcome C and E) Learning Outcomes: This course supports the following ABET Learning Outcomes: C An ability to design a system, component or process to meet desired needs. E An ability to identify, formulate and solve engineering problems G An ability to understand the impact of engineering in a global & societal context K An ability to use the techniques, skills, and modern engineering tools necessary for engineering practice Grading: Mid Term Exam....…………………......................... 20% Final Exam ……………..........................………….. 20% Design Project.....………….…….......................…... 20% Lab Assignments............…………............................ 40%2 A final letter grade will be assigned on the following basis: 90 - 100 A 80 - 89 B 70 - 79 C 60 - 69 D Below 59 F Class Rules: 1. Professional attitude in class is expected from all students. 2. No use of cell phones or MP3 Players allowed during class. 3. Attendance is mandatory. 4. Lab assignments must be submitted IN CLASS at the time they are due. 5. All assignment problems must be presented on individual pages on plain white paper or engineering pad paper (each page must have DATE, NAME). 6. Make-up exams will be strongly discouraged and will only be allowed in the event of an excused absence or illness. In these instances the make-up will be given at the instructor's convenience. 7. Completeness, neatness and legibility in assignments, exams and projects are mandatory. Academic Dishonesty: Cheating in way or form is unacceptable at WVU and may result in an F grade and possible disciplinary action, regardless of overall performance. For definition of "Academic Dishonesty" and code of conduct, refer to the WVU Student Handbook or "Mountie Publication" (http://www.arc.wvu.edu/admissions/integrity.html) and the WVU Undergraduate Catalog. Social Justice: WVU is committed to social justice. I concur with that commitment and expect to maintain positive learning environment based upon open communication, mutual respect and non-discrimination. WVU does not discriminate on the basis of race, sex, age, disability, veteran status, religion, sexual orientation, color or national origin. Any suggestions as to how to further such a positive and open environment in this class will be appreciated and given serious consideration. Lab Assignment Format KNOWN: State concisely what is known about the problem. FIND: State concisely what must be found. SCHEMATIC: Draw a schematic of the physical system being considered. Label important variables. If3 application of the conservation laws is anticipated, represent the appropriate control volume or control surfaces by dashed lines. Be sure to identify processes associated with control volume/surfaces. PROPERTIES: List the solid and/or fluid thermophysical properties used in your solution. Identify the table from the Text and especially the temperature at which the property was selected. ASSUMPTIONS: It is important that you put all the assumptions in one place so that they can be reviewed. At the outset, some assumptions may be obvious, like “steady-state conditions,” etc. But as you begin to model more complicated systems, the assumptions are extremely important to the logic of your analysis. ANALYSIS: Provide in sentence format, comments that make clear the logic and organization of your analysis. Be sure to identify by numbers any figures or equations taken from the Text. DESIGN REPORT(S) I will assign you with an open-ended design problem. You may work in groups (size of groups will be specified later). You will be required to make good engineering assumptions, formulate the problem, come up with a technically and economically feasible design, and decide on construction materials and present simulation results. Towards the end of the semester you will submit a detailed design report, which will decide your grade for the design portion of the final grade. All your work should be presented in a report. Please use drafting package for all your drawings and sketches. PLANNED COURSE CONTENT 1. Introduction to Linear Algebra A. Vectors and Matrix Multiplication B. Solving a System of Equations i.
