摘要：
A new plane element with drilling degrees of freedom is derived in this paper. This membrane finite element can be combined with the plate bending element. The element provides an efficient tool for linear and nonlinear analysis of shells. The element stiffness matrix is obtained from pure deformations-elongations of edges. This approach is very suitable for nonlinear analysis, where the unbalanced forces can be obtained directly from elongations of edges.
