Summary

In the last decades, composite materials are increasingly applied in many branches of industries, due to their higher values of strength and stiffness, superior thermal properties, and reduced weights, which can affect the mechanical performances of beam, plate, or shell structural applications. On the other hand, the discovery of carbon nanotubes (CNTs) or further nano-scale derivatives of carbon, such as graphene, with their oxide, opens a new horizon in the material science, and makes these advanced nano-scale materials an efficient alternative to conventional micro-size reinforcements such as carbon and glass fibers. The use of carbon-based nanofillers as reinforcement phase in polymers enables enhanced properties within nanocomposites, namely, high stiffness, strength, toughness, hardness, heat distortion temperature, and electrical properties in addition to a reduced processing cost due to their exclusive nanostructures. In a context where an increased computational demand is required to solve even more complicated problems, this special issue discusses about high-performance computational strategies and advanced theoretical formulations to solve heat transfer problems; thermal and mechanical stresses (including boundary layer and edge stresses); free vibrations and damping; transient dynamics; bifurcation buckling, local buckling, face-sheet wrinkling and core crimping; large deflection and postbuckling problems; effects of discontinuities (eg, cutouts and stiffeners), and geometric changes (eg, tapered thickness); damage and failure of sandwich structures; optimization and design studies.

    Nonlinear Post-Buckling Stability of Graphene Origami-Enabled Auxetic Metamaterials Plates

    Salwa A. Mohamed, Mohamed A. Eltaher, Nazira Mohamed, Rasha Abo-bakr
    CMES-Computer Modeling in Engineering & Sciences, DOI:10.32604/cmes.2025.061897

    Abstract The nonlinear post-buckling response of functionally graded (FG) copper matrix plates enforced by graphene origami auxetic metamaterials (GOAMs) is investigated in the current work. The auxetic material properties of the plate are controlled by graphene content and the degree of origami folding, which are graded across the thickness of the plate. The material properties of the GOAM plate are evaluated using genetic micro-mechanical models. Governing nonlinear eigenvalue problems for the post-buckling response of the GOAM composite plate are derived using the virtual work principle and a four-variable nonlinear shear deformation theory.

    Advanced Computational Modeling and Mechanical Behavior Analysis of Multi-Directional Functionally Graded Nanostructures: A Comprehensive Review

    Akash Kumar Gartia, S. Chakraverty
    CMES-Computer Modeling in Engineering & Sciences, Vol.142, No.3, pp. 2405-2455, 2025, DOI:10.32604/cmes.2025.061039

    Abstract This review explores multi-directional functionally graded (MDFG) nanostructures, focusing on their material characteristics, modeling approaches, and mechanical behavior. It starts by classifying different types of functionally graded (FG) materials such as conventional, axial, bi-directional, and tri-directional, and the material distribution models like power-law, exponential, trigonometric, polynomial functions, etc. It also discusses the application of advanced size-dependent theories like Eringen’s nonlocal elasticity, nonlocal strain gradient, modified couple stress, and consistent couple stress theories, which are essential to predict the behavior of structures at small scales. The review covers the mechanical analysis of MDFG nanostructures in nanobeams,… More >

    Hygro-Thermo-Mechanical Equivalent Layer-Wise Theory of Laminated Shell Structures

    Francesco Tornabene, Matteo Viscoti, Rossana Dimitri
    CMES-Computer Modeling in Engineering & Sciences, Vol.142, No.2, pp. 1697-1765, 2025, DOI:10.32604/cmes.2025.058841
    (This article belongs to the Special Issue: Theoretical and Computational Modeling of Advanced Materials and Structures-II)
    Abstract This study presents a generalized two-dimensional model for evaluating the stationary hygro-thermo-mechanical response of laminated shell structures made of advanced materials. It introduces a generalized kinematic model, enabling the assessment of arbitrary values of temperature variation and mass concentration variation for the unvaried configuration at the top and bottom surfaces. This is achieved through the Equivalent Layer-Wise description of the unknown field variable using higher-order polynomials and zigzag functions. In addition, an elastic foundation is modeled utilizing the Winkler-Pasternak theory. The fundamental equations, derived from the total free energy of the system, are solved analytically… More >

    Magneto-Electro-Elastic Analysis of Doubly-Curved Shells: Higher-Order Equivalent Layer-Wise Formulation

    CMES-Computer Modeling in Engineering & Sciences, Vol.142, No.2, pp. 1767-1838, 2025, DOI:10.32604/cmes.2024.058842

    Abstract Recent engineering applications increasingly adopt smart materials, whose mechanical responses are sensitive to magnetic and electric fields. In this context, new and computationally efficient modeling strategies are essential to predict the multiphysic behavior of advanced structures accurately. Therefore, the manuscript presents a higher-order formulation for the static analysis of laminated anisotropic magneto-electro-elastic doubly-curved shell structures. The fundamental relations account for the full coupling between the electric field, magnetic field, and mechanical elasticity. The configuration variables are expanded along the thickness direction using a generalized formulation based on the Equivalent Layer-Wise approach. Higher-order polynomials are selected,… More >

    Effect of Process Parameters on the Agglomeration Behavior and Tensile Response of Graphene Reinforced Magnesium Matrix Composites Based on Molecular Dynamics Model

    Chentong Zhao, Jiming Zhou, Xujiang Chao, Su Wang, Lehua Qi
    CMES-Computer Modeling in Engineering & Sciences, Vol.141, No.3, pp. 2453-2469, 2024, DOI:10.32604/cmes.2024.052723

    Abstract The mechanical properties of graphene reinforced composites are often hampered by challenges related to the dispersion and aggregation of graphene within the matrix. This paper explores the mechanism of cooling rate, process temperature, and process pressure’s influence on the agglomeration behavior of graphene and the tensile response of composites from a computer simulation technology, namely molecular dynamics. Our findings reveal that the cooling rate exerts minimal influence on the tensile response of composites. Conversely, processing temperature significantly affects the degree of graphene aggregation, with higher temperatures leading to the formation of larger-sized graphene clusters. In More >

    Chih-Ping Wu, Ruei-Syuan Chang
    CMES-Computer Modeling in Engineering & Sciences, Vol.141, No.1, pp. 917-949, 2024, DOI:10.32604/cmes.2024.052307
    (This article belongs to the Special Issue: Theoretical and Computational Modeling of Advanced Materials and Structures-II)
    Abstract This work develops a Hermitian C differential reproducing kernel interpolation meshless (DRKIM) method within the consistent couple stress theory (CCST) framework to study the three-dimensional (3D) microstructure-dependent static flexural behavior of a functionally graded (FG) microplate subjected to mechanical loads and placed under full simple supports. In the formulation, we select the transverse stress and displacement components and their first- and second-order derivatives as primary variables. Then, we set up the differential reproducing conditions (DRCs) to obtain the shape functions of the Hermitian C differential reproducing kernel (DRK) interpolant’s derivatives without using direct differentiation. The interpolant’s… More >
