摘要：
The results of numerical (in the COSMOS/M environment) and physical simulations of the processes of acoustic-wave propagation in homogeneous linear, flat, and bulk bodies are presented. The characteristics of longitudinal waves as functions of the boundary conditions (rigid and hinged fixation, interface between media) were obtained numerically. The waveguide properties of models near geometrical concentrators in the form of a hole and a crack were investigated under pulsed external actions. The fields of dynamic displacements and stresses were calculated.
