| Abstract: | The compatible displacement analysis is discussed which is suitable for fast analyzing and computing of repaired structure under the background of the repaired structure of civil aircraft. A typical repaired structure is computed and analyzed through this method. When the diameter of rivets, the ratio of doubler thick to skin thick, the size of cutout and the margin of doubler are varied, and the behavior of the stresses at the region of repair is discussed. Being satisfactory, the results obtained are helpful to the repaired structure. |
