The scheme is incorporated in the element formulation to establish new types of non- conforming hexahedral elements designated as NHx and NVHx for the regular element and variable node element, respectively. Non-conforming displacement modes are selectively behavior of the ordinary (conforming)element displacement assumptions to improve the bending behavior of the distorted solid element. 收起
