Topology optimization for design-dependent hydrostatic pressure loading via the level-set method

Abstract: A few level-set topology optimization (LSTO) methods have been proposed to address complex fluid-structure interaction. Most of them did not explore benchmark fluid pressure loading problems and some of their solutions are inconsistent with those obtained via density-based and binary topology optimization methods. This paper presents a LSTO strategy for designdependent pressure. It employs a fluid field governed by Laplace's equation to compute hydrostatic fluid pressure fields that are loading linear elastic … Show more

“…The arch-like optimum solution in Fig. 7 b agrees well with those obtained by previous works that considered this example (Sigmund and Clausen 2007; Picelli et al 2015;Picelli et al 2019;Xia et al 2015;Emmendoerfer et al 2018). These solutions are shown in Fig.…”

“…The solution obtained by RKPM in Fig. 10b is much similar with the ones obtained by Picelli et al (2019) in which the level set method with equivalent nodal loads is used, and Picelli et al (2015) using the BESO method. The main difference between the different approaches is in the number of internal structural members appearing.…”

“…They used the zero level contour of an LSF to represent the loading boundary but did not regard load sensitivities. Recently, Picelli et al [27] proposed a method wherein Laplace's equation is employed to compute hydrostatic fluid pressure fields, in combination with interface tracking based on a flood fill procedure. Shape sensitivities in conjunction with Ersatz material interpolation approach are used within their approach.…”
