Abstract
For three-dimensional finite element modeling, it is necessary to use a solid element taking into account the flexural response and also should be simple for computer storage. One of the elements that can attain the previous requirements is the incompatible (non-conforming) element. In this paper, formulation and algorithm of the developed 3D finite element code of incompatible displacement mode for flexural analysis are presented using 3D 8-noded isoparametric incompatible brick element. Several comparisons and a parametric study have been carried out to verify the incompatible brick element and the developed code. Accurate results have been obtained by the 3D incompatible element in flexural analysis of beams in comparison with the standard element.
