Current research

Scientific

  • Development of an experimental application for FEM structural analysis in C++ with the next features/subgoals:
    • tensor-based matrix form of underlying FEM equations,
    • accumulation of current calculation results in a database to enhance efficiency of tensor expressions,
    • use of C++ template-based metaprogramming for enhancement of efficiency of FEM code,
    • xml-based format of input/output files
      (formerly with the assistance of N.Sokolov);
  • Program implementation and investigation of the of a tensor-based FEM equation for large strains (formerly with the assistance of N.Sokolov).
    Some results (dashed or crosses — init.approx): the von Mises truss under no load (all 3 solutions), an inversed cylinder: circular, square.

Educational
