Finite superelements method for elasticity problems

A Fedorenko Finite Superelements Mehod (FSEM) for linear 3D elasticity problems was considered. It was shown that FSEM equations follows from the Bubnov-Galerkin approximations of a special weak formulation for traces of a solution at superelements boundaries. We present special weak formulation wich natural Bubnov-Galerkin approximation leads to the FSEM. Some applications of the FSEM for the problems of the mechanics of composites are considered.
