Part 1: Course Information

Description

Developed by Kettering University through CAAT seed funding, Design with Aluminum is an introductory course focusing on students' learning of basics of engineering design, properties, manufacturing processes, design aspects and design guidelines along with several real life examples and applications of aluminum alloy materials commonly used in automotive and other applications. The topics will be covered using 'Blended learning' and 'Flipped classroom' approaches. Being an introductory course, only basics of engineering design, mechanical and physical properties, mechanics (stress-strain relationships), and manufacturing processes as applied to body design are introduced. Where applicable, a comparison between steel and aluminum is presented and discussed. The lecture handouts, together with homework assignments, course projects, and exams are designed to train the targeted students in community colleges with basic math, CAD and mechanics experience, for associate degrees and/or certificate programs. A list of a few important references is provided at the end of each course module.

This course is designed to meet over a period of 7 weeks (or more), 2 meetings per week, and 2 hours per meeting.

Prerequisites

Entry level knowledge of mechanical properties of materials, stress and strength considerations, and manufacturing processes; Basic math skills (example: Excel) and basic CAD skills will also help in solving simple examples.

Reference Books  

  • Lecture handouts will be distributed one week in advance 
  • Body Structures by European Aluminum Association, 2013 
  • Design with Aluminum by European Aluminum Association, 2011
  • Specifications for aluminum by Aluminum Association, 1967
  • Various SAE and other conferences papers will be provided for reference

Tools to be used Hand

  • calculator and/or Excel math tool for simple calculations (moderate use)
  • NX or similar CAD tools (minimal use)

Part 2: Course Learning Outcomes (CLOs)
