The Department of Materials Science and Engineering is involved in studying mechanical behaviour of a wide variety of materials ranging from conventional metals and alloys, ceramics and polymers to hybrid materials and biomaterials at different length and time scales. The QIP course on Mechanical Behaviour of Materials is aimed at sharing the pedagogical and research procedures employed at IIT Kanpur. The course comprising of lectures and lab session shall give the participants of learning, teaching and doing research and development the IIT Kanpur way and hopefully aid them in establishing similar procedure at their home institutes.

The course will cover the following topics

  1. Introduction to tensors, stress, strain, co-ordinate transformation. Numerical methods for curve fitting
  2. Introduction to linear elasticity, atomistic origins of elasticity, viscoelasticity, composites
  3. Fundamentals of plastic deformation, Schmid law, Tresca and von Mises criterion, flow rule
  4. Basics of slip and twinning, introduction to dislocations, type and characteristics of dislocations, dislocation energy, interactions and dynamics, dislocation reactions
  5. Strain hardening and strengthening mechanisms, interaction of dislocations with other defects, case studies on engineering materials like superalloys and intermetallics
  6. Fracture and Fatigue, Linear Elastic Fracture Mechanics, Griffith’s criteria, fracture toughness, Environmentally Assisted Fracture (e.g., Stress Corrosion Cracking, Hydrogen Embrittlement), Fatigue Mechanisms, low and high cycle fatigue, Fatigue Testing, S/N Curve, Fatigue Crack Propagation
  7. Creep and superplasticity, Dislocation Creep diffusion creep, Correlation between properties and performance: parametric models, Deformation Mechanism Maps, Creep-fatigue interaction
  8. High strain rate testing, Split Hopkinson Pressure Bar, constitutive equations
  9. Micro-mechanical testing, nano-indentation and micro-pillar testing, in-situ experiments, testing of soft matter, atomic force microscopy
