    Topology Optimization for Variable Thickness Shell-Infill Composites Based on Stress Analysis Preprocessing

    Xuefei Yang, Ying Zhou, Liang Gao, Hao Li
    CMC-Computers, Materials & Continua, Vol.85, No.1, pp. 613-635, 2025, DOI:10.32604/cmc.2025.068756
    (This article belongs to the Special Issue: Optimization Design for Material Microstructures)
    Abstract Inspired by natural biomimetic structures exemplified by femoral bones, the shell-infill composite design has emerged as a research focus in structural optimization. However, existing studies predominantly focus on uniform-thickness shell designs and lack robust methodologies for generating high-resolution porous infill configurations. To address these challenges, a novel topology optimization framework for full-scale shell-filled composite structures is developed in this paper. First, a physics-driven, non-uniform partial differential equation (PDE) filter is developed, enabling precise control of variable-thickness shells by establishing explicit mapping relationships between shell thickness and filter radii. Second, this study addresses the convergence inefficiency… More >

    An Optimization-Driven Design Scheme of Lightweight Acoustic Metamaterials for Additive Manufacturing

    Ying Zhou, Jiayang Yuan, Zhengtao Shu, Mengli Ye, Liang Gao, Qiong Wang
    CMC-Computers, Materials & Continua, Vol.85, No.1, pp. 557-580, 2025, DOI:10.32604/cmc.2025.067761

    Abstract Simultaneously, reducing an acoustic metamaterial’s weight and sound pressure level is an important but difficult topic. Considering the law of mass, traditional lightweight acoustic metamaterials make it difficult to control noise efficiently in real-life applications. In this study, a novel optimization-driven design scheme is developed to obtain lightweight acoustic metamaterials with a strong sound insulation capability for additive manufacturing. In the proposed design scheme, a topology optimization method for an acoustic metamaterial in the acoustic-solid interaction system is implemented to obtain an initial cross-sectional topology of the acoustic microstructure during the conceptual design phase. Then, More >

    Topology Optimization of Orthotropic Materials Using the Improved Element-Free Galerkin (IEFG) Method

    Wenna He, Yichen Yang, Dongqiong Liang, Heng Cheng
    CMC-Computers, Materials & Continua, Vol.83, No.1, pp. 1415-1414, 2025, DOI:10.32604/cmc.2025.059839
    (This article belongs to the Special Issue: Optimization Design for Material Microstructures)
    Abstract In this paper, we develop an advanced computational framework for the topology optimization of orthotropic materials using meshless methods. The approximation function is established based on the improved moving least squares (IMLS) method, which enhances the efficiency and stability of the numerical solution. The numerical solution formulas are derived using the improved element-free Galerkin (IEFG) method. We introduce the solid isotropic microstructures with penalization (SIMP) model to formulate a mathematical model for topology optimization, which effectively penalizes intermediate densities. The optimization problem is defined with the numerical solution formula and volume fraction as constraints. The… More >

    First Principles Calculations for Corrosion in Mg-Li-Al Alloys with Focus on Corrosion Resistance: A Comprehensive Review

    Muhammad Abdullah Khan, Muhammad Usman, Yuhong Zhao
    CMC-Computers, Materials & Continua, Vol.81, No.2, pp. 1905-1952, 2024, DOI:10.32604/cmc.2024.054691
    (This article belongs to the Special Issue: Optimization Design for Material Microstructures)
    Abstract This comprehensive review examines the structural, mechanical, electronic, and thermodynamic properties of Mg-Li-Al alloys, focusing on their corrosion resistance and mechanical performance enhancement. Utilizing first-principles calculations based on Density Functional Theory (DFT) and the quasi-harmonic approximation (QHA), the combined properties of the Mg-Li-Al phase are explored, revealing superior incompressibility, shear resistance, and stiffness compared to individual elements. The review highlights the brittleness of the alloy, supported by B/G ratios, Cauchy pressures, and Poisson’s ratios. Electronic structure analysis shows metallic behavior with varied covalent bonding characteristics, while Mulliken population analysis emphasizes significant electron transfer within the… More >
