“…Figure 14 shows the frequency variation with different embedded depths of the plate for the first five modes. e frequencies clearly decrease (increase) with an increase in the embedded depth for modes 1, 2, and 4. e frequencies of modes 3 and 5 first increase and then decrease, and the inflection point is located at ∼7.5 mm depth, indicating a certain mutation between the embedded depth and the plate stiffness [11,[30][31][32][33].…”

To investigate the mechanical properties of embedded honeycomb plates with high efficiency and accuracy, a new multilayered equivalent finite element method (FEM) model is proposed. A series of FEM numerical studies (modal analysis, static analysis, and shock spectrum analysis) are performed. The goal is to compare the errors produced by the multilayered equivalent method and by existing equivalent approaches. The obtained results indicate that the proposed model shows good agreement with the original plate. Moreover, based on the new model, a parametric study correlating the microstructure parameters (embedded depth/cell size) to modal frequency is proposed, and a multiparameter equation for frequency and embedded depth/cell size is established to serve as a basis for structural optimization design.

Filtering properties and local energy distribution in different classes of periodic micro-structured elastic systems are analysed in this work. Out-of-plane wave propagation is considered in continuous and discrete elastic systems arranged in series and parallel. Filtering properties are determined from the analysis of dispersion diagrams and energy distribution within different phases in the representative unit cell. These are determined analytically by implementing a transfer matrix formalism. The analysis given in the work indicates quantitatively how to couple phases, having discrete and continuous nature, in order to tune wave propagation and energy localisation.

“…foam, honeycomb and balsa wood), the structure thus composed has a static behavior considerably better than the individual parts that make up. Lightweight sandwich constructions are used to increase the specific stiffness, which formulate the strengthening of structures for functional and economic reasons [7,8]. The face carries tensile and compressive stresses, whereas the core carries transverse forces as well as shear stresses [9].…”

Sandwich structures are low-weight and have the best stiffness and a relatively high flexural strength, what makes using them continues to increase rapidly for industrial applications ranging from aeronautics, road vehicles, satellites, ships and civil engineering to mention only a few. The paper presents investigation and analysis of the behavior of composite sandwich beams with polyester resin/glass fibers skins (T800/M300) and aluminum honeycomb core under unsymmetrical bending impact. In this work we propose a numerical study using a calculation software, structural analysis by finite element method (CAST3M), for determining the stresses and displacements. The results which have been obtained after numerical modeling showed that unsymmetrical bending resistance of the sandwich beam is dependent largely on the skins.
