Design of reinforced specified fatigue life capability airframe panels containing notches

Abstract


Calculation procedure of maximum allowable by the fatigue life value of the stress concentration factor (SCF) in reinforced airframe panels containing notches is presented. The problem of reducing the SCF in the passenger airplane wing panel with notches and holes is discussed. The problem is solved by means of interactive simulation and search for the reasonable design alternate basing on the 3D finite element model of the panel.
