Abstract ：
This work proposes a topology optimization method for continuous fiber-reinforced composite (CFRC) structures with additive manufacturing (AM), which realizes the concurrent optimization of material layout and fiber orientation. The residual stress caused by AM process is constrained to avoid the failure of warpage and distortion. The inherent strain method (ISM) is applied to simplify the calculation of residual stress, the Tsai-Wu criterion and P-norm are incorporated to realize structural failure prediction and local constraint aggregation. Several typical instances are adopted to verify the effectiveness of proposed method, which provides a novel solution for the optimization of CFRC structures fabricated by AM.

Abstract ：
Lattice structure can realize excellent multifunctional characteristics because of its huge design space, and the cellular configuration directly affects the lattice structural performance and lightweight. A novel energy-absorbing multifunctional lattice structure with phononic bandgap is presented by topology and parameter optimization in this paper. First, the two-dimensional (2D) cellular configuration is lightweight designed by using independent continuous mapping (ICM) topology optimization method. The 2D cell is reconstructed by geometric parameters and rotated into a three-dimensional (3D) cell by using chiral shape to achieve bandgap. Subsequently, the surrogated model with energy absorption as the object and first-order natural frequency as the constraint is established to optimize a parametric 3D cell based on the Response Surface Methodology (RSM). Finally, the lattice structures are assembled with dodecagonal staggered arrangements to avoid the deformation interference among the adjacent cells. In addition, the lattice structural energy absorption and bandgap characteristics are analyzed and discussed. Compared to Kelvin lattice structure, the optimal lattice structure shows significant improvement in energy absorption efficiency. Besides, the proposed design also performs well in damping characteristics of the high-frequency and wide-bandgap. The lattice structural optimization design framework has great meaning to achieve the equipment structural lightweight and multi-function in the aerospace field.

Abstract ：
Hybrid lattice structures consisting of multiple microstructures have drawn much attention due to their excellent performance and extraordinary designability. This work puts forward a novel design scheme of lightweight hybrid lattice structures based on independent continuous mapping (ICM) method. First, the effective elastic properties of various microstructure configurations serve as a bridge between the macrostructure and the multiple microstructures by the homogenization theory. Second, a concurrent topology optimization model for seeking optimized macroscale topology and the specified microstructures is established and solved by a generalized multi-material interpolation formulation and sensitivity analysis. Third, several numerical examples show that hybrid lattice structures with different anisotropic configurations accomplish a better lightweight effect than those with various orthogonal configurations, which verifies the feasibility of the presented method. Hence, anisotropic configurations are more conducive to the sufficient utilization of constitutive material. The proposed scheme supplies a reference for the design of hybrid lattice structures and extends the application field of the ICM method.

Abstract ：
This paper presents a novel topology optimization method to design graded lattice structures to minimize the volume subject to displacement constraints based on the independent continuous mapping (ICM) method. First, the effective elastic properties of graded unit cells are analyzed by the strain energy-based homogenization method. A surrogate model using quartic polynomial interpolation is built to map the independent continuous topological variable to the effective elastic matrix of the unit cell and set up the relationship between the macroscale structure and microscale unit cells. Second, a lightweight topology optimization model is established, which can be transformed into an explicitly standard quadratic programming problem by sensitivity analysis and solved by dual sequential quadratic programming. Third, several numerical examples demonstrate that graded lattice structures have a better lightweight effect than uniform lattice structures, which validates the effectiveness and feasibility of the proposed method. The results show that graded lattice structures become lighter with increasing displacement constraints. In addition, some diverse topological configurations are obtained. This method provides a reference for the graded lattice structure design and expands the application of the ICM method.

Abstract ：
Aiming at solving the lightweight design problems for bi-disc systems with consideration of the stiffness and strength simultaneously, a two stage topology optimization framework based on independent continuous and mapping (ICM) method is developed. First, topology optimization formulations are established to guarantee the optimized design satisfying the key nodal displacement and stress constraints. Second, an information function is introduced to realize the transformation of the material properties between elements and components. Composite exponential filter functions are selected to establish the relationship between the properties of elements and corresponding topology design variables. Third, approximate explicit quadratic programming model is obtained by the sensitivity analysis and Taylor expansion. In the process of solving, the duality theory is used to establish the approximate dual model with less design variables. Finally, a series of topology optimization design problems for bi-disc systems are presented and discussed to illustrate the robustness and feasibility of the method. This study finds some new torsional bi-disc designs and can also provide some theoretical references for the lightweight topology optimization of a multicomponent system.

Abstract ：
In this paper, a cross-resolution acceleration method for topology optimization is proposed based on deep learning aiming at achieving precise and high-efficiency geometrically non-linear structure design. We develop a cross-resolution Pix2pix neural network (CR-Pix2pix NN) to build the high-dimensional mapping between the low-resolution intermediate configuration (IC) and the corresponding high-resolution optimized configuration. Architecture of CR-Pix2pix NN is composed of a cross-resolution generator and Markovian discriminator. The cross-resolution geometrically non-linear dataset utilized to train the deep learning model is created by solving stress constrained topology optimization model established by independent continuous mapping (ICM) method. The pre-trained CR-Pix2pix NN is capable of accurately predicting the high-resolution optimized configuration by inputting the low-resolution IC with the only one iteration step. Furthermore, the hyperparameters of the developed model are discussed to ensure the performance in accuracy and computational efficiency. The proposed method can be generalized to other precise topology optimization scenarios and engineering design.

Abstract ：
Hybrid lattice compliant mechanisms (HLCMs) composed of multiple microstructures have attracted widespread interest due to their superior compliant performance compared to the traditional solid compliant mechanisms. A novel optimization scheme for HLCMs is presented using the independent continuous mapping (ICM) method. Firstly, the effective properties of multiple orthogonal and anisotropic lattice microstructures are obtained by taking advantage of homogenization theory, which are used to bridge the relationship between the macrostructure layout and microstructure recognition. Then, a new parallel topology optimization model for optimizing HLCMs is built via a generalized multi-material, recognizing interpolation scheme with filter functions. In addition, the characterization relationship between independent continuous variables and performance of different elements is established. Sensitivity analysis and linear programming are utilized to solve the optimal model. Lastly, numerical examples with a displacement inverter mechanism and compliant gripper mechanism demonstrate the effectiveness of the proposed method for designing HLCMs with various lattice microstructures. Anisotropic lattice microstructures (ALMs) significantly facilitate the efficient use of constitutive properties of materials. Hence, HLCMs consisting of various ALMs achieve superior compliant performance than counterparts comprising different orthogonal lattice microstructures (OLMs). The presented method offers a reference to optimize HLCMs, as well as promotes the theoretical development and application of the ICM method.

Abstract ：
An intelligent microstructural design method based on deep learning is proposed considering performance indicators that contains boundary information and homogenized elastic modules. Microstructure dataset is established by random boundary method and homogenization method. Random boundary method is proposed to design microstructures under given boundary information, and homogenization method is utilized to acquire homogenized elastic modules. A generative and adversarial network with gradient penalty is developed to establish the high-dimensional mapping between performance indicators and microstructure. The Wasserstein distance is imported to overcome mode collapse. Numerical simulation shows that the pre-trained network successfully achieved corresponding microstructure design by given performance indicators.
