| Abstract: | The boundary condition of local displacement and force at the damage place was simulated based on the finite element model of the whole aircraft.The crack damages in the high stress zone of wing integral panel were analyzed and the effect of different sizes on the strength of integral panel was studied.The result was presented through the relationship between damage size and residual load factor,residual strength factor,which offers an assessor the reference for the damage degree of brattle aircraft. |
