Özet:

In this thesis, wing structural characteristics of a medium-range transport aircraft are investigated by using a finite element package called I-DEAS. The three dimensional solid model of the wing is constructed and thereafter by using one and two dimensional finite elements, a mixed mesh is generated on the model. After the application of the boundary conditions, the dynamic and static analyses are performed and the solutions for the wing are obtained for with and without fuel cases. The results are presented in terms of the natural frequencies and mode shapes for the dynamic analysis and the displacements and stresses for the static analysis. These results are further analyzed in order to find the effect of the fuel and to investigate the behavior of the wing.
