Residual Strength Analysis of a Cracked Stiffened Panel with Stochastic Factorsin Fastener Flexibility

摘要

In this report, a residual strength analysis of a cracked stiffened panel wasconducted on the basis of the displacement compatibility method, which is generally used as a handy tool. Stochastic factors in fastener flexibility are considered in the analysis by Monte Carlo simulation. The report outlines the displacement compatibility method, a method of taking in stochastic factors into account, some results of differences in stochastic distribution models in fastener flexibility, and some results of the analysis. The author shows that the stochastic flexibility coefficients in rivet fastening affect the residual strength estimation of a cracked stiffened panel considerably.
