    • Application of symbiotic cellular automaton method to describe the contrast media 

      Dmitriev, Andrey I.; Dimaki, Andrey V.; Psakhie, Sergey G. (CIMNE, 2013)
      Text en actes de congrés
      Accés obert
      The method of symbiotic cellular automaton, which combines two approaches to describe the simulated media – the method of conventional cellular automaton and method of movable cellular automaton, has been developed for ...

    • Features of interface formation in crystallites under mechanically activated diffusion. A molecular dynamics study. 

      Nikonov, Anton Yu.; Dmitriev, Andrey I.; Konovalenko, Ivan S.; Kolubaev, Evgeniy A.; Astafurov, Sergey V.; Psakhie, Sergey G. (CIMNE, 2015)
      Comunicació de congrés
      Accés obert
      In this paper, we carried out investigation of behavior of the material under loading condition identical those used in FSW using molecular dynamic method. The loading was modelled by a rigid rotating “tool” that movies ...

    • Molecular dynamics modelling of boundary migration in bicrystals under nanoburnishing 

      Dmitriev, Andrey I.; Nikonov, Anton Yu. (CIMNE, 2015)
      Text en actes de congrés
      Accés obert
      The paper reports the molecular dynamics simulation results on the behavior of a copper crystallite in local frictional contact. The crystallite has a perfect defect-free structure and contains a high-angle grain boundary ...

    • Molecular-dynamics investigation of nanoburnishing process 

      Kuznetsov, Viktor P.; Nikonov, Antony Y.; Dmitriev, Andrey I. (CIMNE, 2011)
      Text en actes de congrés
      Accés obert
      It is well known that the burnishing process affects the surface characteristic, namely: surface roughness, surface hardness, wear resistance, fatigue resistance and increased maximum residual stress in compression. ...

    • Numerical study of conditions for subsurface shear instability under contact interaction 

      Dmitriev, Andrey I.; Kuznetsov, Viktor P.; Tarasov, Sergey Yu. (CIMNE, 2015)
      Comunicació de congrés
      Accés obert
      Numerical modeling of nanostructuring burnishing has been carried out to reveal the limiting values of process parameters, which serve both to provide the appropriate surface quality and positive deformation-induced ...

    • Theoretical investigation of the dynamics of friction stir welding process by movable cellular automaton method 

      Astafurov, Sergey V.; Shilko, Evgeny V.; Kolubaev, Evgeny A.; Dmitriev, Andrey I.; Nikonov, Anton Yu.; Psakhie, Sergey G. (CIMNE, 2015)
      Text en actes de congrés
      Accés obert
      The paper is devoted to development of a new approach to study of friction stir welding (FSW) process on the mesoscopic scale. This approach is based on computer-aided simulation by movable cellular automaton (MCA) method. ...
