This paper presents a new simple four-node quadrilateral shell element with 24-dof which can be used to analyze thick and thin shell problems. This element which is developed from DKMQ plate element using the Naghdi/Mindlin/Reissner shell theory can take into account warping effects and coupling bending-membrane energy. This element, called DKMQ24, passed patch tests for membrane, bending and shear problems. It has also successfully passed benchmark tests in the case of thick and thin shells without shear locking. Moreover, the numerical results obtained with DKMQ24 converge toward the reference solution.
