Energy release rate and criticality of multiscale defects kinetics

摘要

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.
