摘要：

An extension of the concept of error iii the constitutive relation is proposed in the case of Mindlin plate finite element computations. In a first stage, loads and momentum densities in equilibrium are calculated on each element edge as the sum of densities derived from the finite element solution and densities with a resultant equal to zero on each edge. Then, the statically admissible stress resultants are determined within each element. Both of the two stages allow an optimization of the statically admissible fields in order to obtain a more accurate error.
