Abstract
The study presents an adaptive finite element formulation for four node curved shell elements based on Rei ssner-Mindlin theory. It is of particular interest to provide adaptive schemes which take into account the real geometry of shell structures e.g. given by CAD data and for which also the real geometry of the boundary condition is considered. Thus for linear shell analysis different error estimates are given for the discretization of the geometry ( a priori indicator) and the solution of the finite element analysis ( a posteriori indicator). Some applications and the efficiency of the algorithm are demonstrated using selected examples.
