Evolution of stress-strain state in the structural hierarchy of blocks in the geomedia under uniaxial and biaxial loading
Based on the experimental study of the rock samples and artificial geomaterials with the same structure and using the speckle correlation method the article presents a detailed investigation on the peculiarities of the evolution of the stress-strain state at a microlevel. An effect of low-frequency micro-deformation processes under slow (quasi-static) disturbances in the artificial geomaterials has been revealed. The experimental investigation presented in it falls in the physico-mechanical causes of the emergence of the focal areas of seismic catastrophes.
Key words: simulation, rock samples, wave-deformations, speckle-method, source zone, failure.
