Applications of an improved estimator of the constitutive relation error to plasticity problems
L. Gallimard, P. Ladeveze and J.P. Pelle
Abstract
This paper presents several applications of an improved estimator of the constitutive relation error (CRE) for plasticity problems. The cumulative aspect of the CRE estimator with respect to time is analyzed and we propose a first analysis of the local effectivity indexes of the CRE estimator in plasticity.
Key Words
finite element method; plasticity; error estimation; local qualities.
