In order to calculate the fracture parameters (Stress intensity factor) in a complicated 3-dimention aircraft model with damage in the aircraft panel, a new two steps global-localhierarchical analysis strategy is used. This paper primarily describes the development andapplication of advanced computational analysis techniques to determine stress intensity factors forthe damaged panels based on the two steps hierarchical analysis strategy from global to 3-D localmodel, the bulging deformation of crack can be considered in the local model. A fracture parametercalculation programme based on automated global-local procedure to simulate cracked aircraftpanel tests is developed for the hierarchical strategy. This programme may create models of twostages, transfer boundary conditions, calculate and obtain fracture parameter automatically. Finally,this paper presents some of the experimental data and the calculated fracture parameters arecompared with the experimental results
