Paper Title:
Nonlinear Correlated Interaction of Mesodefects and Transition to Macrofracturing
  Abstract

The following experimental data are presented and discussed: a) the explosion-like nucleation of micro- (meso) cracks; b) the dependence of the scale of local “microcatastrophe” on the relation between the released strain energy and the dissipative properties of the nearest environment; c) the determinative influence of the dissipative properties on the rate of redistribution of local stresses. The presented data evidence that every event of defect nucleation that takes place at either micro- or mesoscale level in the heterogeneous solid examines the energy absorbtion properties of the whole system. Future localization of the macroscopical failure is of “accidental type”, that is results from random, active formation of the ensemble of micro- and mesocracks in different localities as a consequence of the decrease of the dissipative capability of surrounding volume.
