Abstract

In this paper, an anomaly resolving strategy is presented for such cases where the nominal and robust compliances are the same in the volume-constrained continuous topology optimization with directionally uncertain loads. In this investigation, the parametric normally and uniformly distributed expected compliance and the non-parametric total-compliance-variance are used as robustness measures. It will be proved by experimental evidence, that in the anomalous cases the result of the nominal-compliance minimization and the results of the minimization of the investigated robust measures form a pareto optimal point, therefore the volume-percentage increasing is the only way of the design robustness improving.
