Description	The nanoindentation test of a single crystal of tungsten is simulated by a multiscale model based on a 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 copper crystal under a superimposed hydrostatic stress. The calculated value of the critical indentation depth is in a very good correspondence with that of the experimentally observed pop-in on the load-displacement curve. The value of the Young modulus of tungsten received from the reduced modulus of elasticity of the original Hertz model is also in an excellent agreement with experimental data. This offers us a possibility to assess the concentration of alloying and impurity elements in the surface and sub-surfa The nanoindentation test of a single crystal of tungsten is simulated by a multiscale model based on a nonlinear elastic finite element analysis coupled with both ab initio calculations of the ideal shear strength and crystallographic considerations.
