Abstract

The residual strength prediction and assessment of panels with MSD is very important to aged airplane. This paper presented the load-sharing parallel system reliability model to assess residual strength of this kind of structure. The model treated the structure as a load-sharing parallel system with different type components since different ligaments have different area. The probability distribution of the residual strength of system was derived by Monte Carlo simulation method. The model was verified by test results and most relative errors to test results for this model are about 10 percent.
