In this paper are being considered deals the questions measuring of non-metallic dissipative properties of heterogeneous materials and products from them acoustic shock method based on the dependence of the damping rate fluctuations and the propagation velocity of acoustic waves in the material. Since while sound waves are striking through the heterogeneous material pulse shape sensing changes significantly, it is necessary to establish the laws of this transformation. The research of features formation of acoustic fields in heterogeneous non-metallic materials has been conducted and has been offered a mathematical model of transformation while sound waves are striking through the material, taking into account its physical and mechanical characteristics. |
