A survey of structural and multidisciplinary continuum topology optimization: post 2000 (2014, background): “Bruyneel and Duysinx (2001, 2005) outline the challenges of self-weight loads in density-based topology optimization with a minimum compliance objective.”
Topology optimization using a mixed formulation: An alternative way to solve pressure load problems (2007, methodology): “the discussion in [22]) and we thus attribute the problems to the self-weight issue and not to the proposed interpolation scheme.”
Topology optimization involving thermo-elastic stress loads (2010, methodology): “This is just like the similar phenomenon observed in body force problem (Bruyneel and Duysinx 2005; Gao and Zhang 2009a). The optimization structures are shown in Fig. 9. The configurations have similar topologies and are in good accordance with the results of Rodrigues and Fernandes (1995)”
Stress-constrained topology optimization with design-dependent loading (2012, unknown): “Since a self-weight problem is subject to the intermediate-density artifact observed by Bruyneel and Duysinx (2005), a linear density switch limit of ρC = 0.25 was imposed in the Young’s modulus redefinition (18).”
Component and system reliability-based topology optimization using a single-loop method (2010, methodology): “Du and Chen (2004) proposed a method called SORA (sequential optimization and reliability assessment), which employs a single-loop strategy that decouples the outer design optimization from the inner reliability analysis.”
