The influence of the uniaxial static stress on creep in the polycrystalline rocks was studied. The study was performed using the original method of loaded complex oscillator. The theory of the method is proposed, The measurements were performed for polycrystalline khibinite. The advantages of the method before traditional methods for studying of physical mechanisms of creep are demonstrated.
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.
