Originální abstrakt
The nanoindentation test in the dislocation free crystal of nickel is simulated by nonlinear elastic finite element analysis coupled with both ab initio calculations of the ideal shear strength and crystallographic considerations. The onset of microplasticity, associated with the pop-in effect identified in experimental nanoindentation tests (creation of first dislocations), is assumed to be related to the moment of achieving the value of the ideal shear strength for the nickel crystal. The calculated value of the related indentation load lies within the range of experimentally observed pop-ins in the nickel crystal.
