Abstract: 

This paper considers the quadrilateral membrane elements with drilling degree of freedoms in the viewpoint of algebraic patterns. The presence of the free parameters in components of the stiffness matrix unifies the methods and provides the opportunity to improve the element performance. The element stiffness matrix decomposes into basic and higher order parts. The basic stiffness matrix satisfies the convergence requirements and has one free parameter. The higher other stiffness matrix, constructed by Assumed Natural Deviatoric Strain approach with 24 parameters, satisfies the accuracy and stability requirements. The element stiffness matrix has not any spurious modes and does not lock in the analysis. This template can be correlated with another methods and obtain the signature of the elements.
