The student

  • has the basic understanding of mechanical processes to explain the relationships between externally applied load and materials strength.
  • can describe the main empirical materials models for fatigue and creep and can apply them.
  • has the physical understanding to describe and explain phenomena of failure.
  • can use statistical approaches for reliability predictions.
  • can use its acquired skills, to select and develop materials for specific applications.
