The size effects upon shock plastic compression of nanocrystals

For the first time a theoretical analysis of scale effects upon the shock plastic compression of nanocrystals is implemented in the context of a dislocation kinetic approach based on the equations and relationships of dislocation kinetics. The yield point of crystals $\tau_y$ is established as a quantitative function of their cross-section size $D$ and the rate of shock deformation as $\dot\varepsilon$, $\tau_{y}\sim\dot\varepsilon^{2/3}D$
