Learning outcomes

After successful completion of the course, students are able to understand basic concepts from tensorial calculus, linear theory of elasticity, and a relation between elastic properites and crystal symmetries. The students learn about dislocations, their classification and relation to macroscopic material properties.

Subject of course


  1. Vectors, matrices and tensors
  2. The stress and strain tensors
  3. The fourth rank tensor of elastic constants
  4. Other tensors describing physical properties of crystals

Theory of dislocations:

  1.  Properties dislocations: 
    • Continuum idealisation vs. discrete view
    • Perfect vs. imperfect dislocations
    • Curved dislocations
  2. Elastic fields of straight dislocations in linear elasticity: 
    • Stress fields
    • Energy of dislocations
    • Partial dislocations, stacking faults
  3.  Non-linear effects: 
    • Peierls-Nabarro Model
    • Atomistic structure of dislocation core
  4.  Dislocations in real materials: 
    • Dislocation sources
    • Observation, TEM principles of dislocation imaging
    • Dislocation motion, work-hardening
    • Critical thickness for dislocation-free thin epitaxial films
