'Materials Selection in Mechanical Design' is a course offered in the B. Tech. in Mechanical Engineering program at School of Engineering, Amrita Vishwa Vidyapeetham.
Unit 1
Overview of materials properties - modulus, tensile. Fatigue, creep strengths, toughness, hardness, fracture toughness, damping capacity, thermal, oxidation, corrosion and wear resistances.
Materials property charts. Materials families and classes - metals, ceramics, glasses, polymers, elastomers, composites, foams, natural.
Unit 2
Basis of materials selection. Design of components - functions, constraints, objectives and free variables. Selection process - translation, screening, ranking, supporting information. Illustration of the principles with examples - heat sink, overhead electrical transmission line, tie rod, light stiff beam. Multiple constraints and objectives - case studies. Design of hybrid materials - case studies.
Unit 3
Case studies in materials selection for various applications - oar, table leg, flywheel, kiln walls, passive solar heating, heat exchangers, bearings, springs, pressure vessel.
Principles of process selection and classification - casting, forging, moulding, fabrication, welding, joining, machining, powder processing, composite processing. Illustration of the principles with case studies.
Multiple constraints and objectives - case studies.Design of hybrid materials - case studies.
