　Development of numerical simulation schemes, especially finite element method (FEM), for the behaviors of structure and solid material under loadings is our main interest. The followings are our recent topics:

  • Image-based FEM: To combine FEM and 3-D digital images captured by X-ray CT for the prediction of fracturing processes in composite materials,
  • Convex-type FEM formulation: To simplify multi-physics FEM formulations using the classical thermo-dynamics theory for the prediction of electro-magneto-mechanical behaviors of smart materials,
  • Massively-parallel algorithm: To accelerate the computational speed of FEM using GPU and MPI-cluster machines, that is based on the typical "data structure and algorithm".

　From educational aspect, education for prospective engineers is equally important. We have been standing on the point, "For the engineers not well-understanding CAE, using convenient commercial CAE software may cause serious mistakes. More important is mastering material and structural mechanics and doing simple mechanical experiments. Leaning practical mathematics and physics is next...". Thus, combination of research and education may be also our topic.
