In this paper, some considerations on eight node isoparametric shell elements are described. A formulation of the element stiffness matrix and a calculation procedure which reduce computation are presented. The effects reducing the order of integration of the element stiffness matrix are verified by some numerical examples. The limit of the application of the element to thin shell analysis is investigated by numerical examples and some criteria for the usage of the element are discussed. A calculation method of nodal stresses which is consistent with reducing the order of integration of the element stiffness matrix is presented. The presented method, the method which uses the conventional strain matrix and Hinton's method are investigated by some numerical examples.
