In engineering designs such as in buildings, bridges, automobiles, aircraft bodies, points of failure are of critical importance to the designers and researchers. The course of this failure has always been attributed to the structural engineering components being subjected to different stresses and loading systems. This paper analyses deflection pattern in aircraft wing under various loading systems. Two-dimensional standard deflection (flexural) equation was used in the modeling of a typical aircraft wing similar to that of an Airbus A320 wing. Finite element method, one of the numerical methods was adopted in the model development which was based on the classical plate theory and plane stress assumptions. The model was then used to carry out analysis on the wing which was taken as a thin plate. The wing was discretized with triangular and rectangular meshing. JAVA code was utilised in solving the model algorithm which was also made to be interactive. The model analysed different cases with different boundary conditions and loading conditions. Two cases were analysed and deflection along X, Y and XY–axis for each case were generated. Results obtained established that the greater the load, the higher the deflection obtained in the aircraft wing under different loading conditions. However, for edges and nodes with fixed and roller support, higher loadings is required for deflection to occur
