Course Description: This course presents the internal structures and resulting behaviors of materials used in engineering applications, including metals, ceramics, polymers, composites, and semiconductors. The emphasis is upon developing the ability both to select appropriate materials to meet engineering design criteria and to understand the effects of heat, stress, imperfections, and chemical environments upon material properties and performance. Laboratories provide opportunities to directly observe the structures and behaviors discussed in the course, to operate testing equipment, to analyze experimental data, and to prepare reports. (C-ID ENGR 140B).
Objectives
Upon successful completion of this course, the student should be able to:
- Explain the relationship between the internal structure of materials and their macroscopic properties.
- Explain methods (intentional or unintentional) of altering the structure of materials by mechanical, chemical, or thermal means in order to change material properties.
- Illustrate the various systems for classifying materials, and compare differences in properties among material classes that derive from differences in structure.
- Gather data from reference sources regarding the properties, processing, and performance characteristics of materials, and use it as a basis to recommend appropriate material(s) to meet engineering design criteria.
- Measure material properties and/or evaluate processing treatments using standard materials testing equipment and techniques. (Lab)
- Write laboratory reports that communicate the collection, analysis, and interpretation of experimental data according to professional engineering standards. (Lab)
