Abstract
The influence of the uniaxial static stress on the Young’s modulus and on the internal friction of the polycrystalline rocks was studied. It was showed, that the effects of micropores and microcracks on the nonlinear elasticity and unelasticity of material are different. This makes possible different control of such parameters as microporosity and microcracking. The study was performed using the original method of loaded complex oscillator.
