“…Consequently, there is no need to use higher order quadrature for the evaluation of the p‐norm stress. Further, we do not observe unstable solutions as predicted or reported in the works of Duysinx and Sigmund and Lian et al…”

“…It possesses the advantages of using explicit boundary representation for yielding functionally optimized geometries with maximum design freedom (with respect to a given discretization). Previously, the DSC method has been applied to the shape and topology optimization of structural compliance minimization problems as well as stress minimization . In this paper, it is further developed and applied to the optimization of Stokes and Navier‐Stokes flow problems, with support of hole splitting and merging.…”

“…Previously, the DSC method has been applied to the shape and topology optimization of structural compliance minimization problems 15,16 as well as stress minimization. 17,18 In this paper, it is further developed and applied to the optimization of Stokes and Navier-Stokes flow problems, with support of hole splitting and merging. Although the proposed approach yields stable results for simple energy dissipation objectives, a new regularization scheme is proposed to control feature sizes and to ensure smoothed optimized designs for more advanced problems.…”

“…O problema contínuo de otimização topológica com restrição de tensão foi inicialmente abordado em Duysinx e Bendsøe (1998), onde a abordagem baseada em densidade é empregada para a obtenção de estruturas de mínima massa que respeitam um critério de falha em tensão estabelecido a priori. Desde então, o problema baseado em tensão ganhou bastante popularidade na literatura (AMSTUTZ; NOVOTNY, 2010; AMSTUTZ; NOVOTNY; NETO, 2012;BRUGGI, 2008;BRUGGI;DUYSINX, 2012;SIG-MUND, 1998;FANCELLO, 2014;FANCELLO, 2019;FANCELLO, 2006;FANCELLO;PEREIRA, 2003;TORSTENFELT;KLARBRING, 2013;KIYONO;REDDY, 2016;KIYONO et al, 2016;LE et al, 2010;LIAN et al, 2017;LEON et al, 2015;LONG;NOVOTNY, 2016;LUO;KANG, 2013;PARÍS et al, 2009;FANCELLO;BARCELLOS, 2004;PICELLI et al, 2018;NOVOTNY, 2017;SVÄRD, 2015;TROYA;TORTORELLI, 2018;QIAN, 2018), devido principalmente a necessidade de se considerar requisitos de projeto mais realísticos na otimização estrutural.…”
