Investigation of scenarios of fracture foci formation in materials and media of different rheology is quite important for estimation of life cycle and resource of different constructions as well as for prognosis of their fracture.
At present time the all-known fact is that all materials and media including plastics, metals, ceramics, composites, construction and building materials as well as geomedia and rocks represent the multiscale nonlinear dynamic systems. Loaded solids and media as typical nonlinear dynamic systems demonstrate the characteristic features of evolution: the dynamic chaos, self-organized criticality, local and global loss of stability starting from the formation of mesoscopic scale cracks up to the main cracks. Theoretical and experimental investigation of features of stress-strain state fluctuations near the middle-trend in different media (the jerky flow and fracture of brittle specimens) showed its conformance to the Guttenberg-Richter law. These facts prove the community of fracture scenarios both for materials of different engineering constructions as well as geomedia at large scales and specimens at small scales.
Studying deformation and fracture of materials and media as nonlinear dynamic systems permits to excurse from private details of internal structure and specific mechanisms of non-elastic strain and define the most common characteristics of mechanical response near the critical states. One of the central goals of investigation of mechanical response of loaded solids and media as nonlinear dynamic systems is to identify the precursors of transition to the superfast critical stage.
