Summary: Sandwich panels, consisting of cores and facesheets, are widely used in blast- and impact-resistant design due to their excellent energy absorption capacity and lightweight. This article extensively reports the influence of variations in the geometry and material of the components on the overall dynamic response of sandwich panels, and provides a comprehensive review on the behavior of sandwich panels with different shapes of cores and facesheets, core grading, and the use of stiffeners. The review also discusses available experiment/test setups and finite element tools for conducting blast and impact tests/analysis on sandwich panels.

Summary: This research investigates the buckling behavior of hybrid-honeycomb sandwich (HHS) cylindrical shells under hydrostatic pressure. The HHS shells consist of ceramic-metal functionally graded (FG) layers on the outer and inner surfaces, with a layer of lightweight hybrid-honeycomb material in the center. The results show improved buckling resistance, stability, and enhanced energy absorption due to the unique microstructure of the auxetic materials.

Summary: A novel cladding sandwich panel with aluminum foam-filled tubular cores was proposed to enhance impact resistance, with a study showing that the aluminum foam and tubular cores dissipate the majority of impact energy. Improvements in impact force and energy absorption were found by filling aluminum foam, increasing density, and increasing contact area between impactor and panel. Impact position had little effect on energy absorption when away from panel edge, and similar thickness between flat steel plate and tubular cores generally resulted in better energy absorption performances.

Summary: The effect of gel-filling on the transverse compressive response of a hexagonal honeycomb is investigated. It is found that gel-filling changes the deformation mode and increases the pinch load due to the presence of incompressible gel-core and membrane tension within the honeycomb walls.

Summary: This study investigated the low-velocity impact behavior of honeycomb-core sandwich panels through experimental and numerical analysis, identifying two distinct failure modes. Structural parameters such as facesheet thickness, core height, honeycomb cell size, and cell wall thickness were found to significantly influence the impact performance of the sandwich panels. Optimizing the structural design by controlling these parameters can enhance perforation resistance and energy absorption capacity.

Summary: This study investigated the performance of sandwich panels with two different core materials and aluminum alloy face sheets under low-velocity impact through experimental and numerical analysis. The contact and impact resistance were examined by analyzing the changes in contact force and kinetic energy. The findings showed that the face-sheet thickness was an important parameter affecting the impact behavior, with polystyrene foam being more effective in preventing impact damage.

Summary: This paper investigates the thermal buckling and free vibration of a viscoelastic functionally graded sandwich shell with a tunable auxetic honeycomb core. The viscoelastic behavior of the skins and core is modeled using the complex modulus approach and the elastic-viscoelastic correspondence principle. The Poisson's ratio of the auxetic honeycomb core can be adjusted based on an angle parameter. The equations of motion are derived using Hamilton's principle, and an analytical solution for a simply supported shell is obtained using Navier's solution procedure. The effects of geometry parameters, temperature rise, and tunable auxetic honeycomb core parameters are studied.

Summary: The amplitude-dependent damping characteristics of all-composite sandwich (ACS) plates with a hexagon honeycomb core (HHC) filled by soft foam (SF) are investigated. The solutions of nonlinear fundamental frequencies, mode shapes, and damping ratios of HHC-SF-ACS plates are obtained theoretically. It is found that increasing the Young's or shear moduli of foam material and the filling ratio of SF can improve the damping property of the composite plates significantly.

Summary: A beam finite element model is proposed for static and free vibration analyses of FGM sandwich beams with viscoelastic nonlinear material behavior. Different viscoelastic frequency-dependent laws, Timoshenko 1st order, and Reddy's higher order shear models are used. The stiffness matrix is nonlinear and frequency dependent. The study shows that beam behavior is sensitive to the loss factor, and damping properties are nonlinearly dependent on the power law index. Boundary conditions affect vibration modes.

Summary: This study investigates the effect of viscoelastic properties in foam-filled sandwich panels under low-velocity impact loading. A finite element (FE) model using ABAQUS software is developed to study the impact of considering and ignoring time-dependent behavior of composite facesheets and foam core. Material constitutive equations, damage characteristics, and failure modes are defined using a FORTRAN user-subroutine VUMAT. Experimental tests are conducted to characterize the material behavior of polyurethane foam and glass/epoxy composite material. The results of numerical simulations are validated through low-velocity impact tests on sandwich panels, showing good agreement with experimental results, and highlighting the importance of considering viscoelastic properties for accurate modeling.

Summary: The buckling instability of architectured plates with constant aspect ratios is investigated in this study. It is found that the geometry of individual blocks plays a significant role in increasing the buckling resistance of plates, while the material of the blocks has a greater influence on the failure of the structure compared to the frictional coefficient.

Summary: The thermomechanical and barrier properties of modified montmorillonite/polypropylene nanocomposites were investigated, showing that increasing clay content decreases the self-diffusion coefficient of the material and can hinder the degradation of mechanical properties even when temperature and water content increase. The modeling using molecular dynamics and force field calculations was validated by comparing glass transition temperature values obtained from simulations with experimental values, demonstrating good agreement.
