A New Method Applied to the Quadrilateral Membrane Element with Vertex Rigid Rotational Freedom
In order to improve the performance of the membrane element with vertex rigid rotational freedom, a new method to establish the local Cartesian coordinate system and calculate the derivatives of the shape functions with respect to the local coordinates is introduced in this paper. The membrane eleme...
