The B-spline field approximation method is used to construct discrete models of thick shells. The shell formulation is developed from first principles, using assumptions that are useful in this numerical context. The transverse shear strains, rather than the rotation variables, are used as independent variables for the purpose of discretization. Examples of the application of this formulation are presented.
