The finite element method has been used in many areas, including in the process of designing and testing aircraft structures. This method has been developed into software that is easier to use. This method uses small elements consisting of nodal to describe objects to be modeled so that objects with complex geometries can be more easily modeled. <br /> <br /> <br /> The model is made wingbox CN 235 where the base of the wing will be clamped then given the force on the wingtips. The modeling still assumes the connections made are perfectly connected. The observed area of displacement and tension is the lower wing skin with 17 observation points. in addition, the geometry made refers to previously modeled modeling with data from PTDI and some direct measurement data in the FTMD hangar using ruler and calipers. <br /> <br /> <br /> After the results obtained, displacement and voltage, then compared with experimental data Digital Image Correction and dial gauge that has been done before. So that obtained the result of numerical modeling of displacement 33,3 mm and voltage 51,7 MPa for force 3000N. <br />
