“…In 2000, the FEM has been used for the validation of an aircraft fuselage structures [13]. In 2011 two FE reduced models have been used to characterize the dynamic behavior of the boosters for the launcher Arian V [14]. The first FE model has been built using only beam elements, while the second FE model includes shell and beam elements for the structure and solid elements for the fuel.…”

This work investigates the effects of composite materials and non-structural masses on the dynamic behavior of space structure components and whole space vehicle. A refined one-dimensional model has been used in the analyses, and the effects of composite materials and of the fuel mass introduced as non-structural masses have been considered. The adopted refined one-dimensional Finite Element Model has been developed using the Carrera Unified Formulation. This numerical tool allows to develop a variable kinematic displacement field over the beam cross-section, that is, a set of Lagrange (LE) expansions polynomials was adopted for the crosssectional displacement field approximation. The use of such one-dimensional models leads to the so-called component-wise (CW) approach in which stiffeners and plate are modeled using the same one-dimensional kinematic. Static and free vibration analysis of space structural components and complete space structures have been performed. Both compact and thin-walled structural configurations have been considered. The results have been assessed using analytical solutions or refined three-dimensional Finite Element Models. Composite materials and non-structural masses, e.g. the fuel mass or payload, have been included in the analysis. The results show the capability of the present model to provide a quasi three-dimensional solution with a low computational cost. The refined kinematic allows composite materials to be investigated accurately.

“…In reinforced structure analyses, 2D elements are usually used to discretize a plate, while 1D elements are used for stringers [19,20]. In other cases, the 2D elements are also used for stringers [21,22].…”

This work has the aims to assess and compare the behavior of different Finite Element Models in a free-vibration analysis of reinforced structures. The effects of the aspect-ratio and cross-sectional shape of the stringers have been analyzed using both classical and refined FE. One-and two-dimensional classical finite element models, as well as refined one-dimensional elements, derived using the Carrera Unified Formulation, have been considered in an analysis of reinforced structures. The accuracy and efficiency of these models have been investigated. A three-dimensional model has been used as a reference solution. Three different modeling approaches have been considered in the present work. Two approaches are based on classical models provided by commercial tools: the first uses two-dimensional elements for both a plate and stringers, while the second uses two-dimensional elements to simulate the plate and the beam elements for the stringers. The third approach uses a refined one-dimensional model, based on the Carrera Unified Formulation. This refined one-dimensional model considers a variable kinematic displacement field over the beam cross-section. In the present work, Lagrange polynomials are used to describe the cross-sectional displacement field. The use of a Component-wise modeling approach allows the stiffeners to be modeled as independent entities. The Component-wise approach was first assessed and convergence was then evaluated. The performances of these models in the analysis of reinforced structure were then compared with those from classical models. The use of refined one-dimensional models allows stiffener modes to be investigated. The results show that this approach is comparable to a full threedimensional solution. The use of classical one-and two-dimensional models does not allow the local deformation of reinforcements to be taken into account. Therefore, these models cannot be considered accurate when the aim of the analysis is to investigate the local mode.
