Mechanical Properties of Materials

Stress and strain of material; Elastic deformation: Youngs modulus, Poissons ratio, stress-strain relation, stiffness/compliance matrix; Dislocations: Edge/screw/mixed dislocation, burgers vectors, twining, stress field of dislocation, dislocation interaction; Plastic deformation of single and polycrystalline materials: Schmids law, plastic flow; Inelastic deformation: Viscosity, deformation of inorganic glasses, deformation of noncrystalline and crystalline polymers; Mechanical fracture: ductile and brittle facture, creep, fatigue; Testing methods.
