Note

  1. Introduction
  2. linear elasticity
  3. classification of stresses
  4. Failure due to plasticity
    • tensile test
    • dislocations
    • hardening mechanisms
    • guidelines for dimensioning
  5. composite materials
  6. fracture mechanics
    • hypotheses for failure
    • linear elasic fracture mechanics
    • crack resitance
    • experimental measurement of fracture toughness
    • defect measurement
    • crack propagation
    • application of fracture mechanics
    • atomistics of fracture

The student

  • has the basic understanding of mechanical processes to explain the relationship between externally applied load and materials strength.
  • can explain the foundation of linear elastic fracture mechanics and is able to determine if this concept can be applied to a failure by fracture.
  • can decribe the main empirical materials models for deformation and fracture and can apply them.
  • has the physical understanding to describe and explain phenomena of failure.
