Energy release rate and criticality of multiscale defects kinetics
Configuration mechanics of solid with defects (microcracks, microshears) was used for statistical description of multiscale defect interaction, presentation of out of equilibrium free energy release rate and defects kinetics, which reveals specific type of criticality structural scaling transition. According to this transition defects kinetics occurs as generation of collective modes of defects that have the nature of self similar solutions for defects kinetic equations. It is showm using original "in situ" experiments that spatial temporal scenario of collective modes leads to specific fractographic pattern on fracture surface and self similar material responses in wide range of load intensity.
