Geofizicheskiy Zhurnal| Zusammenfassung: | The computer simulation of the process of nonlinear wave propagation in a structured geophysical medium with elastic-plastic interaction between the structure elements is conducted. It is found that during the wave propagation in a chain of the discrete elements its amplitude decays to the threshold value, when the interaction between the elements becomes elastic, and then the wave is transformed into a soliton-like wave with the threshold amplitude. The deformation diagrams of the massifs at different plastic threshold values are plotted. It is demonstrated that a decrease of the plastic threshold results in an increase of the dissipative properties. |
