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.

This work deals with the application of the micromechanical Gurson-Tvergaard (GT) model to the determination of the residual strength of analuminumflat stiffened panel (2024 T3) with a central through crack, by means of finite element simulations. The load condition is represented by a monotonic traction along the direction orthogonal to the crack plane. The used Finite Element code is WARP 3D®, which allows simulating ductile damage propagation by considering the GT model. Numerical results have been compared with experimental ones available in literature. In the second part of the work, a home madeprocedurefounded on the SDI (Stochastic Design Improvement) technique is presented and applied to the improvement of the residual strength properties of the considered panel.
