Summary
The process of failure preparation in model material has been studied. To constrain the deformation and fractures to a certain zone within the sample the biaxial compression tests have been chosen. During the deformation the cross-like zone, consisting of a great number of small cracks, appeared followed by the development of macrofracture in the central part of the specimen. The strong minimums in velocity of ultrasonic waves, changes of strain rate, and self-electric potential reliably pointed to the approaching moment of failure.
