Stochastic Improvement of the Residual Strength of a Stiffened Panel

Abstract:

The objective of robust design is to optimize the mean of a given target variable and to minimize the variability that results from uncertainty represented by “noise” factors. A recent strategy for robust design is based on stochastic processes, which has resulted in a new design technique called “stochastic design improvement” (SDI). In this work a home-made procedure is presented, which is based on the SDI technique and which is illustrated with reference to a case study which aims to increase the residual strength of a cracked stiffened aluminum panel.
