摘要：
A very simple way to obtain a quadrilateral shell element is to write membrane and bending stiffness matrices for a flat geometry and add them. This basic membrane-plus-bending element can be modified to incorporate membrane-bending coupling and to accommodate a geometry in which the four nodes are not coplanar. The present paper develops a 24 degree of freedom quadrilateral shell element and concurrently provides a status report on the formulation method by pointing out what works and what does not. Numerical results are good: the element is not the best available four-node shell element in all test cases but is far from the worst.
