A large amount of microdeffects of different types are formed during dynamical destruction of elastic-plastic materials. A separate description of each microfailure is very laborious and practically impossible. Therefore mechanics of continual (or scattered) destruction has been developed recently, which governing equations introduce some internal variables, characterizing microfailure development. MIMOZA technique implements a kinetic model for viscous plastic NAG destruction, updated to enable the description of destructed materials. Numerical simulation results for some experiments based on it are presented.
