Abstract
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.
