Abstract
Presented in this paper is numerical modeling of polycrystalline aluminum behavior under the weak shock waves. Plastic deformation is considered as a process of shear stability loss on the different scale levels: micro, meso, and macro. A dislocation kinetics equation describes micro scale processes. For the meso scale deformation to be simulated we use two different models. One of them takes into account a generation of plastic shears on grain boundaries and the other allows us to describe `independent rotation' of mesofragments. On the macro level we calculate impact interaction the aluminum flyer plate with perfectly rigid wall. The results of 2D calculations are reported and discussed.
