Introduction of hierarchy of physical models of materials. Fundamental continuum mechanics and thermodynamics. Lattices and crystal structures. Quantum mechanics. Empirical atomistic models of materials. Molecular statics. Atomistic foundations of continuum concepts: classical equilibrium, statistical mechanics, microscopic expressions for continuum fields, molecular dynamics. Multiscale methods: multi scale modelling, atomistic constitutive relations for multi lattice crystals, atomistic-continuum coupling: static methods, non-zero temperature and dynamics. Overview of fabrication techniques for today's nanostructures and modern experimental methods at the nano scale.
