1. Thin-walled profiles loaded by tension, compression, shear, torsion and bending. 2. Linear stability of compressed bars. Combined load. Excentric tension and compression. Oblique bending. 3. Beams on elastic foundations. 4. Basics of plasticity. Approximations of stress-strain diagram, ultimate load carrying capacity, residual stresses. 5. Plates, characteristic features of stress distribution. Rotationally symmetrical plates. 6. Shells and membranes, membrane and bending stresses. Cylindrical shell. 7. Thick-walled cylindrical vessels, elastic and elastic-plastic deformations. Shrink-fitted joints. 8. Rotating discs. Stress in a disk without and with a central opening, disk of constant stresses. 9. Contact stress (contact of balls and cylinders, stresses and deformations). 10. Failure of structures. Behavior of brittle and ductile bodies with notches. Brittle fracture. 11. Fatigue: high cycle and low cycle. Stress concentration, influence of notches, Woehler curve, random loading, accumulation of damage. 12. Principles of fracture mechanics (criterion of rapid crack propagation, subcritical crack growth). 13. Fundamentals of mechanics of polymeric materials.

Learning outcomes
|
The aim of the subject is to acquaint students with more complex ways of stressing and failure of machine parts. To teach the students to calculate stresses and deformations in the elastic and elastic-plastic field, to assess the safety of a component and to dimension it for load-bearing capacity and required service life.
