Discover the structure of the materials that make up our modern world and learn how this underlying structure influences the properties and performance of these materials.
Structure determines so much about a material: its properties, its potential applications, and its performance within those applications. This course is the second in a three-part series from MIT’s Department of Materials Science and Engineering that explores the structure of a wide variety of materials with current-day engineering applications. Taken together, these three courses provide similar content to MIT’s sophomore-level materials structure curriculum.
Part 2 provides an introduction to the study of crystallography. We begin by looking at crystals and their symmetries in two dimensions. Then, we expand into three dimensions, exploring the underlying crystalline structures that underpin most of the materials that surround us. Finally, we look at how tensors can be used to represent the properties of three-dimensional materials, and we show how these change as a function of the crystalline symmetry.
If you would like to explore the structure of materials further, we encourage you to enroll in Part 1 and Part 3 of the course.Crystal structure image by User: Materialscientist on Wikimedia.
