This paper addresses the study of the quality and objectivity of responses obtained with the distinct formulations (symmetric and non-symmetric) of the discontinuity embedded finite elements, as well as with the local continuum approach (smeared model), in which the softening law dependent on the element size is combined with a scheme to track the discontinuity path. The study is based on the concepts of kinematic and static consistency of the embedded discontinuity formulations. (C) 2010 CIMNE (UPC). Published by Elsevier Espana, S.L. All rights reserved.
