Shape optimization of the X0‐specimen for biaxial experiments
weak equilibrium reads
δR = K δu + P δs + H δhn ! = 0 and therefore, δu = −K−1 (P δs + H δhn) = S δs, (6)
which yields the sensitivity matrix S connecting the structural response with geometric design changes [...] PAMM 20, (2020). [4] J. Liedmann and F.-J. Barthold, Structural and Multidisciplinary Optimization 61(6), 2237-2251 (2020). [5] J. Simo, T. J. R. Hughes, Computational Inelasticity, (2000).
