Abstract

The method of eigenvalue approximation is used to numerical calculation for the study of influence of volumetric pores and flat defects on resonant spectrum of mechanic oscillation of powder materials with porosity of 0 to 0,24. The received solutions allowed to exhibit the character of changes of free vibration resonant spectrum of a cube sample depends of porosity.
