Concurrent topology optimization of multiscale structures with multiple porous materials under random field loading uncertainty (2017, methodology): “¼ δij: ð19Þ Based on the linear superposition principle, the key idea in the literature (Zhao and Wang 2014a, b) is to introduce f0 ¼ μY xð Þ; f1 ¼ ffiffiffiffiffi λ1 p ψ1 xð Þ; :::; fM ¼ ffiffiffiffiffiffi λM p ψM xð Þ; ð20Þ as M + 1 deterministic design independent boundary load fields based on…”
