Triple-wave ensembles in a thin cylindrical shell - диплом по математике

 

Тезисы:

  • 5 Ginsberg JM (1974) , Dynamic stability of transverse waves in circular cylindrical shell, Trans.
  • Triple-wave resonant ensembles.
  • NBThe resonant interactions of -type are inherent in cylindrical shells only.
  • The main idea is to trace the propagation of a quasi-harmonic signal - is the wave stable or not?
  • Generally, such instability is associated with the degenerated four-wave resonant interactions.
  • NBThe wave modes entering -type triads can propagate in the same spatial direction.
  • From the theoretical viewpoint this phenomenon can be treated within several independent scenarios.
  • The wave pulse at frequency of 1120 Hz was generated.
  • 1 Bretherton FP (1964) , Resonant interactions between waves, J. Fluid Mech., 20, 457-472.
  • High-frequency bending and two low-frequency bending waves () .
