Abstract

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 fix- ation, 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.
