Singularity of elastic characteristics of zeolite, quartzite, sandstone sio2, expanded polystyrene

Summary The internal friction background Q-10, which carry on the information about the changing of the elastic strains fields in rocks, was studied. Elastic waves pulses were discovered from microfractures that connected with elastic balance in minerals. The elastic anisotropy integral coefficient (A_μ ) and the polarization angle – the deflection of elastic displacements vector U from wave normal direction n φ_P =(U ,n ) and are the most universal characteristics of anisotropy and testify about anisotropic deformation e at the rock hydrostatic compression P. The data are obtained from elastic constants Cmnkl sandstones SiO2, limestones CaCO3.
