Physico-mathematical modeling and informational technologies| Summary: | The propagation of harmonic elastic waves in infinite solid with the system of disc-shaped inclusionsof low rigidity is investigated. The problem in the frequency domain is reduced to the systemof boundary integral equations by the functions of displacement jumps on the inclusion. Usingnumerical method, the analysis of the distribution of dynamic stress intensity factors of separationin the vicinity of the inclusions depending on the wave number of inclusions at various distancesbetween defects and the various ratio between the elasticity moduli of the matrix environment anddisc-shaped inclusion is carried out. |
