Structural Optimization of Fiber-Reinforced Material Based on Moving Morphable Components (MMCs)

Structural Optimization of Fiber-Reinforced Material Based on Moving Morphable Components (MMCs) Fiber-reinforced composite materials have excellent specific stiffness, specific strength, and other properties, and have been increasingly widely used in the field of advanced structures. However, the design space dimensions of fiber-reinforced composite materials will expand explosively, bringing challenges to the efficient analysis and optimal design of structures. In this paper, the authors propose an explicit topology optimization method based on the moving morphable components for designing the fiber-reinforced material. We constrain the intersection area between components to guarantee the independence of each component and avoid the situation that one component is cut by other components. Adding the fiber orientation angle as a design variable, the method can optimize the structural layout and the fiber orientation angle concurrently under the given number of fiber layers and layer thickness. We use two classical examples to verify the feasibility and accuracy of the proposed method. The optimized results are in good agreement with the designs obtained by the 99-line code. The authors also popularize the proposed method to engineering structure. The results manifest that the proposed method has great value in engineering application. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Mechanica Solida Sinica Springer Journals

Abstract

Fiber-reinforced composite materials have excellent specific stiffness, specific strength, and other properties, and have been increasingly widely used in the field of advanced structures. However, the design space dimensions of fiber-reinforced composite materials will expand explosively, bringing challenges to the efficient analysis and optimal design of structures. In this paper, the authors propose an explicit topology optimization method based on the moving morphable components for designing the fiber-reinforced material. We constrain the intersection area between components to guarantee the independence of each component and avoid the situation that one component is cut by other components. Adding the fiber orientation angle as a design variable, the method can optimize the structural layout and the fiber orientation angle concurrently under the given number of fiber layers and layer thickness. We use two classical examples to verify the feasibility and accuracy of the proposed method. The optimized results are in good agreement with the designs obtained by the 99-line code. The authors also popularize the proposed method to engineering structure. The results manifest that the proposed method has great value in engineering application.
