Abstract

The new Quadrilateral Area Coordinate (QAC) method is a powerful tool to construct 2D finite element models [1]. Compared with the traditional models using isoparametric coordinates, these new models are less sensitive to mesh distortion. Various elements based on QAC method have been successfully developed, among which the 4-node quadrilateral membrane element AGQ6-I is a typical one [2].
