Based on existing theoretical results, closed forms of the sensitivities are presented. A zero-order term is introduced in the equilibrium equations, which allows for adapting the obtained sensitivities to the context of topology optimization of plates under elastic support and free vibration condition as well. The resulting analytical formulae are used together with a level-set domain representation method to devise a simple topology design algorithm. Several finite element-based representative numerical experiments are presented showing its applications to the compliance minimization and eigenvalue maximization of Kirchhoff as well as Reissner-Mindlin plate structures under bending effects.pdfeninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Topological derivativeCompliance minimizationEigenvalue maximizationinfo:eu-repo/semantics/articleCarvalho, Fernando Soares de; Ruscheinsky, D.; Giusti, Sebastián MIguel; Anflor, Carla Ttatiana Mota; Novotny, Antonio Andréhttps://creativecommons.org/licenses/by-nc-nd/4.0/https://doi.org/10.1007/s00158-020-02710-4
