Abstract
A brief review of the research activity provided during the last three decades in the Laboratory of Mechanics of Nanomaterials and Theory of Defects at the Institute for Problems in Mechanical Engineering of Russian Academy of Sciences in the field of micromechanics of strength and plasticity in nanostructured materials is presented. It covers the works aimed at explanation and theoretical description of the following features in mechanical behavior of these materials: deviations from the classical Hall-Petch law, homo- and heterogeneous nucleation of dislocations, grain boundary sliding and mechanisms of its accommodation, rotational deformation, deformation twinning, deformation-induced grain growth and refinement, and interaction between deformation and fracture processes. Some most important and interesting results are discussed and compared with available data of experimental studies and computer simulations.
