Engineering 45: The Structure and Properties of Materials
Engineering 45: The Structure and Properties of Materials (Spring 2014, UC Berkeley). Instructor: Professor J. W. Morris. Properties of Materials - Application of basic principles of physics and chemistry to the engineering properties of materials. Special emphasis devoted to relation between microstructure and the mechanical properties of metals, concrete, polymers, and ceramics, and the electrical properties of semiconducting materials.
