Single crystalline, polycrystalline and amorphous materials – single crystals: unit cell, crystal
systems, Bravais lattices, directions and planes in a crystal, Miller indices – inter-planar
distances - coordination number and packing factor for SC, BCC, FCC, HCP and diamond
structures - crystal imperfections: point defects, line defects – Burger vectors, stacking faults –
role of imperfections in plastic deformation - growth of single crystals: solution and melt growth
techniques.

Crystal Physics

Elasticity – Stress-strain diagram and its uses - factors affecting elastic modulus and tensile
strength – torsional stress and deformations – twisting couple - torsion pendulum: theory and
experiment - bending of beams - bending moment – cantilever: theory and experiment –
uniform and non-uniform bending: theory and experiment - I-shaped girders - stress due to
bending in beams

Properties Of Matter

Transfer of heat energy – thermal expansion of solids and liquids – expansion joints - bimetallic
strips - thermal conduction, convection and radiation – heat conductions in solids – thermal
conductivity - Forbe‘s and Lee‘s disc method: theory and experiment - conduction through
compound media (series and parallel) – thermal insulation – applications: heat exchangers,
refrigerators, ovens and solar water heaters
