Stress Analysis of Fuel Access Cut out of the bottom skin of a transport aircraft

Sartaj Patel, Mahesha.K, Harish E.R.M

Aircraft is symbol of a high performance mechanical structure with a very high structural safety record. In this an attempt had made to find the maximum tensile stress location in the bottom skin of transport aircraft by considering the behaviour of side spars for bending and ribs for transverse load. The component wing box with the access cut out in the bottom skin is considered for the analysis in this the behaviour of each rib and side spars is calculated or known. The maximum tensile stress location is identified. This location is the stress concentrated areas. In this location should be identified and the crack can be avoided.
