Experimental examples of shock-induced structural instabilities in solids, which are
nucleated in the process of multiscale dynamic deformation, are considered from the position
of methods of registration. The criterion for nucleation of instability, which includes the particle
velocity variation at the mesoscale, supposes that instability arises when rate of change of the
velocity variation within the shock front becomes higher than rate of change of the mean
particle velocity.
