ME 471 - Computer Aided Engineering Analysis and Design
Catalog Data: ME 471: Computer Aided Engineering Analysis and Design. 3(3,0).
Students are exposed to geometric and solid modeling, finite elements,
optimization, and rapid-prototyping. Students design an artifact, represent it on
the computer, analyze it using FEA, then optimize before prototyping it.
Emphasizes the use of computer-based tools for engineering design. The World
Wide Web is used for reporting. Preq: Numerical methods and programming
experience or consent of instructor.

Objectives 1 :
1. To provide the students with a foundation in computer aided design. [B,C,D,E,F,J]
2. To produce knowledgeable users of CAD systems. [B,C,D,E,F,J]
3. To introduce the students to Finite Element Techniques. [B,C,D,E,F,J]
4. To widen the exposure of the students to contemporary design tools such as optimization and Rapid
5. To make the students aware of the capabilities and limitations of computer design tools for
Pre/Co-requisites by Topic:
1. Numerical Methods (root finding, matrix algebra, integration, differentiation). (ME 205)
2. Machine Design (free body diagrams, stresses, failure criteria, fatigue). (ME 306)
3. Engineering Graphics (projections, sketches, tolerancing). (EG 209)

Letters in brackets refer to the ME Program Educational Objectives.
7. Software tutorials. (6 hours)
8. Tests. (3 hours)
In addition to homework, the design project aims at integrating the material taught in class into one
complete design process. Students are asked to select some artifact to design. They submit a proposal
describing the artifact they select. Simpler objects to represent will require a more rigorous analysis and
optimization phase. Students represent the selected artifact on a CAD modeler (IDEAS or Pro-
Engineer), analyze it or part of it on a finite element program (IDEAS, ANSYS, ABAQUS), apply some
optimization or guided iteration algorithm to improve the artifact, and then build it or a scale model of it
on a rapid prototyping or CNC machine. Project reports are turned in on the web.
Students write their own programs. They learn to use a CAD package, a FEM package, optimization
routines, rapid prototyping software as well as create web pages.
