Nature and Properties of Materials




2L-0T-0P-0A (6 Credits)



This compulsory course is designed to give the undergraduate students a broad understanding of common materials related to mechanical engineering with an emphasis on the fundamentals of structure-property-application relationships in metals, polymers, and ceramics. The course will also introduce the students to a few advanced materials in engineering applications. Essentially, this course will lay the foundation for all courses in Mechanical Engineering.

Course content

Introduction to Materials, Materials Testing and Properties, Mechanical Properties of Materials, Material Selection for Mechanical Design, Crystal Structures, Metals and Metallic Alloys, High strength and High temperature Superalloys, Engineering Ceramics, Polymers, Composite Materials: Polymeric, Ceramic and Metal Matrix Composites, Smart Materials.
