The course objectives for the student
To develop an understanding of the impact of modern materials on the performance of products that are encountered daily, such as bicycles, beverage containers, and sports equipment.
To develop an understanding of the classes of engineering materials (metal alloys, polymers, ceramics and composites), with an emphasis on their properties and their uses.
To understand how the materials selection process fits into the product design, development and manufacturing process used by industry today. To come to appreciate that product cost and quality play a key role in the materials selection process.
To recognize that environmental regulations (emissions), and societal pressures (energy, safety) can strongly influence the adoption of new technologies and alternate materials.
To discuss the competition of alternate materials for the same applicationSlide5

1. Engineering materials and their propertiesKey points
Enormous range of engineering materials
Types of material properties
Range of properties within and among materials classes
Development of new materials and their impact on design
Failure to select suitable materials can lead to failure of engineering structures and systems
Some failures can be quite spectacular
