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.
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.
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.
