In this investigation, a gradient deficient beam element of the absolute nodal coordinate formulation is generalized to a curved beam for the analysis of multibody systems and the performance of the proposed element is discussed by comparing with the fully parameterized curved beam element and the classical large displacement beam element with incremental solution procedures. It is demonstrated by several numerical examples that the use of the proposed element leads to better element convergence as compared to that of the fully parameterized element when thin beam problems are considered. It is also important to note that fully parameterized elements are required for correctly describing of shear and cross-section deformations and such effect becomes significant when thick beams are considered.
