Recovery procedures in error estimation and adaptivity. Part II: Adaptivity in nonlinear problems of elasto-plasticity behaviour
B Boroomand, OC Zienkiewicz - Computer methods in applied mechanics …, 1999 - Elsevier
The first part of this paper [1] discusses in some detail the use of recovery procedures for
stress, strain or gradients for efficient error estimator and the methods of arriving at adaptive,
h, refinement. In this paper we extend such procedure to deal with elasto-plasticity and
discuss in detail some special features of such computation.

Two types of procedures are currently available for deriving error estimators. They are either
Residual based or Recovery based. The residual based error estimators were first
introduced by Babuska and Rheinboldt in 1978 [1] and have been since used very
effectively and further developed by many others. Here substantial progress was made as
recently as 1993 with the introduction of so called residual equilibration by Ainsworth and
Oden [2]. The recovery based error estimators are, on the other hand, more recent having …
