ABSTRACT

Two related effects are predicted for monocrystals with a single active slip system: (1) the appearance of surface corrugations due to the stress-driven rearrangement instability (SDRI) and (2) the increase of the yield threshold for small specimens. In addition, for the systems under study, we (1) establish the appropriate expression of a chemical potential and (2) establish the key quantitative formula to be verified in the suggested experiment on the SDRI.
