Abstract
This paper presents an extension to plasticity problems of a new error esti mator on the constitutive relation which was introduced by P. Ladeveze in a recent paper. Numerical experiments show that this enhanced error estimato r can lead to a significant improvement in the effectivity indexes in the c ase of anisotropic meshes, or when perfect plasticity is approached.
