Unit I (8 lectures)
Introduction to Engineering Materials:Types of Materials: Metals, ceramics, polymers, semiconductors and composites and their structure, properties, and typical applications. Bonding and Structure: Metallic, covalent, ionic, and van der Waals bonds; implications for material behaviour. Crystallography: Study unit cell configurations, crystal lattices, grain boundaries, and common defects like vacancies and dislocations. Mechanical Behaviour: study of stress-strain curves, modulus of elasticity, yield and tensile strength, ductility, hardness, brittleness, toughness and fatigue; Nanomaterials: Properties at the nanoscale, top-down vs. bottom-up fabrication.
Unit II (8 lectures)
