This paper deals with a posteriori estimation of finite element error and adaptivity. In particular, an error estimator based on stress recovery by enforcing compatibility over local patches of elements is applied to guide adaptive analyses. Various numerical results of adaptive refinement are given, which show the efficiency and reliability of the proposed approach.

Abstract
This paper deals with a posteriori estimation of finite element error and adaptivity. In particular, an error estimator based on stress recovery by enforcing compatibility over local patches of elements is applied to guide adaptive analyses. Various numerical results of adaptive refinement are given, which show the efficiency and reliability of the proposed approach.File in questo prodotto:
