Consistency and correctness evaluation of shear deformable anisoparametricformulations

The first two of the quartet, completeness, continuity, consistency and cor rectness conditions, required for the development of robust displacement ba sed finite elements are well understood as far as the anisoparametric eleme nts are concerned. When such elements are formulated (primarily for accurac y due to their improved consistent load and mass capabilities) by incorpora ting transverse shear deformation effect, it becomes necessary to study the next two of the quartet-(field) consistency and (variational) correctness aspects and to explore further their susceptibility for spurious effects su ch as locking, stress oscillations etc. Such a study on a typical anisopara metric element formulation is presented in this paper, (C) 1999 Elsevier Sc ience Ltd.
