Notizen:
The following experimental data are presented and discussed: a) the explosion-likenucleation of micro- (meso) cracks; b) the dependence of the scale of local “microcatastrophe” onthe relation between the released strain energy and the dissipative properties of the nearestenvironment; c) the determinative influence of the dissipative properties on the rate of redistributionof local stresses. The presented data evidence that every event of defect nucleation that takes placeat either micro- or mesoscale level in the heterogeneous solid examines the energy absorbtionproperties of the whole system. Future localization of the macroscopical failure is of “accidentaltype”, that is results from random, active formation of the ensemble of micro- and mesocracks indifferent localities as a consequence of the decrease of the dissipative capability of surroundingvolume
