| Learning Outcomes |
Competences |
| Students know and understand the basic methods of strength assessment of mechanically loaded structural parts and materials. They are proficient in analyzing simple structural elements of machines, devices or plants, and are able to calculate whether the structural parts and materials can resist the applied static and dynamic loads, i.e. do not fail due to fracture and do not suffer damage due to deformation.

| Skills |
Knowledge |
Students are able to
- analyze general stress and strain states (k4),
- derive and apply material stiffness values (k3),
- derive and apply material strength criteria (k3),
- analyze and evaluate stresses at notches of structural parts (k4, k5),
- analyze and evaluate cracks in structural parts (k4, k5),
- analyze and evaluate cyclic loadings of structural parts (k4, k5),
- analyze compressive loads acting on beam-like structures (k4).
|
- Material behavior and constitutive laws (material constants, Hooke’s law, thermal strains, failure criteria)
- Foundations of notch stress analyses (stress concentrations, contact mechanics, bearing pressure)
- Foundations of fracture mechanics (stress intensity, K-concept, fracture toughness)
- Foundations of fatigue strength analysis (cyclic fatigue tests, notch effect, size effect, damage accumulation)
- Introduction to stability theory of elastic structures (column buckling)
