“…Despite the wealth of attractive properties of TWFC with great potential as the material for both flexible and rigid aerospace, automotive, and civil engineering structures, such as reflectors, booms, satellites, sandwich structures, space membrane skeletons, turbines, geotextiles, reinforced concretes, etc. [ [8] , [9] , [10] , [11] , [12] , [13] ], their thermally-induced responses are scarcely reported in literature. In space structure applications, thermal performance is key in the material selection to ensure the longevity of service under various thermal loads, for instance, solar radiation exerted extreme temperature changes and gradients [ 11 ].…”

“…Isogeometric analysis (IGA), which was first proposed by Hughes et al [1], uses the same basis functions for geometric and computational models to integrate computer-aided design (CAD) and engineering analysis, is becoming an efficient numerical method. IGA has been successfully employed in the computation of various domains, such as vibration [2,3], beams and shells [4,5], fatigue modeling [6][7][8], fluid and fluid-structure interaction (FSI) [9][10][11][12], and structural optimization [13][14][15][16][17], because of the advantages of IGA, such as low computational cost and high accuracy.…”

In isogeometric analysis (IGA), the boundary representation of computer-aided design (CAD) and the tensor-product non-uniform rational B-spline structure make the analysis of three-dimensional (3D) problems with irregular geometries difficult. In this paper, an IGA method for complex models is presented by reconstructing analysis-suitable models. The CAD model is represented by boundary polygons or point cloud and is embedded into a regular background grid, and a model reconstruction method is proposed to obtain the level set function of the approximate model, which can be directly used in IGA. Three 3D examples are used to test the proposed method, and the results demonstrate that the proposed method can deal with complex engineering parts reconstructed by boundary polygons or point clouds.

“…The abovementioned shape and topology optimization methods are based on the finite element method (FEM), some limitations of the FE approach include the disconnection between analysis and geometric models, low continuity between the elements and low efficiency of high-order elements. These limitations are successfully addressed by a new method called isogeometric analysis (IGA) [Hughes, Cottrell and Bazilevs (2005)], which directly uses the basis functions of a computer aided design (CAD) model as the shape functions of analysis model, IGA has since been used in a variety of domains [Benson, Bazilevs, Hsu et al (2011); Hsu and Bazilevs (2012); ; Wang, Benson and Nagy (2015); Yan, Deng, Korobenko et al (2017); Deng, Wu, Yang et al (2018)]. In the last decade, IGA has been adopted for both shape and topology optimizations, which provides several advantages over the established methods.…”

Isogeometric analysis (IGA), an approach that integrates CAE into conventional CAD design tools, has been used in structural optimization for 10 years, with plenty of excellent research results. This paper provides a comprehensive review on isogeometric shape and topology optimization, with a brief coverage of size optimization. For isogeometric shape optimization, attention is focused on the parametrization methods, mesh updating schemes and shape sensitivity analyses. Some interesting observations, e.g. the popularity of using direct (differential) method for shape sensitivity analysis and the possibility of developing a large scale, seamlessly integrated analysis-design platform, are discussed in the framework of isogeometric shape optimization. For isogeometric topology optimization (ITO), we discuss different types of ITOs, e.g. ITO using SIMP (Solid Isotropic Material with Penalization) method, ITO using level set method, ITO using moving morphable components (MMC), ITO with phase field model, etc., their technical details and applications such as the spline filter, multi-resolution approach, multi-material problems and stress constrained problems. In addition to the review in the last 10 years, the current developmental trend of isogeometric structural optimization is discussed.
