The quadrilateral area coordinate (QAC) method is a new tool for developing quadrilateral finite element models. Compared with those traditional elements using isoparametric coordinates, models formulated by QAC method are less sensitive to mesh distortion. In this paper, a family of quadrilateral m

## a b s t r a c t The introduction of the quadrilateral area coordinate (QAC) membrane elements has generated more heat than light on the subject of why distorted membrane elements perform very poorly. The canonical guidelines for construction of robust elements are continuity and completeness. It
