Special Issue Information

Dear Colleagues,

The research in composite materials and structures is closely related to symmetry. For example, symmetric stacking sequences are mostly used to manufacture composite components, and most composite structures are symmetrical in configuration. The study of the symmetry and asymmetry of composite materials and structures is a critical issue. Symmetric components or structures made of composite materials are widespread in automotive, civil engineering, aeronautics, and astronautics industries. Moreover, ideal composite materials can be obtained through the design and control of symmetrical, periodic meso-structure and micro-structure, and novel material properties such as lightweight materials, negative Poisson's ratio materials, and even metamaterials can be obtained. From an analytical point of view, symmetry/asymmetry phenomena provide a convenient way to simplify and establish numerical methods, which may lead to interesting results.

This Special Issue invites researchers to submit original research papers and review articles related to composite materials and structures in which theoretical or practical issues of symmetry are considered. All analytical, experimental, and numerical studies with considered validation are welcome. The topics of interest include but are not limited to:

  • Symmetric and asymmetric structures or components;
  • Symmetry in lightweight structure design;
  • Symmetry in the mechanical response of composite materials;
  • Symmetric and asymmetric microstructure of composite materials (design, characterization, and analysis);
  • Symmetry in metamaterials;
  • Symmetry in bio-inspired composite materials;
  • Symmetry in discretely assembled composite materials;
  • Symmetry in multifunctional composite materials;
  • Symmetry in the fabrication of composite materials;
  • Numerical models of the symmetry of composite materials.

An equivalent theoretical homogenization method was proposed for composite sandwich cylinders subjected to pure bending. Firstly, based on a homogeneous orthotropic layer hypothesis, the trapezoidal corrugated sandwich core was found to be equivalent in a homogenization orthotropic layer with the nine equivalent mechanical properties. Then, Lekhnitskii’s theory, based on a unified connection parameter method, was introduced and applied in the equivalent composite sandwich cylinder. The method developed by Lekhnitskii is suitable for arbitrary combinations of winding layers with different winding angles and materials. Additionally, the bending stiffness of the equivalent sandwich cylinder could be calculated. By developing user subroutine of UMAT, the numerical calculation results were in a good agreement with the results of the proposed method. Further, according to the Hill–Tsai strength criterion and the maximum strain criterion, parametric study was done for specified bending stiffness and specified bending strength. The results show that the influence of core parameters on the specified bending stiffness and strength are lower than that of the skin parameters. Additionally, larger skin thickness and smaller winding angles could improve the specified bending stiffness and specified bending strength of the composite corrugated sandwich cylinders.
