“…In terms of the stiffness and strength of honeycomb panels, sandwich panels with the following types of core are much stronger: coating (Kavermann and Bhattacharyya 2019;Smardzewski and Jasińska 2016), lattice truss (Jin et al 2015;Xu et al 2016), pyramidal (Qi and Ma 2018;Xiong et al 2014a, b;Xu et al 2015), kagome (Klimek et al 2016) cubic or cubic + octet (isomax) (Yazdani Sarvestani et al 2018). Wang (2019) made a comprehensive overview on the development of the innovative honeycomb-based structures in the past two decades. The author suggested that innovative honeycomb will still be a hotspot in the field of impact resistance, packing, blast protection, and other engineering applications in the future.…”

The research determined the resistance to compression and low velocity impact of wood-based sandwich panels, the face sheet made of high-density fiber board, and high pressure laminate, while its auxetic lattice core was made by 3D printing using LayWood bio-composite filament. The core's auxetic property (i.e. exhibiting negative Poisson's ratio) was observed within the planes parallel to the facings. The ability of particular types of multilayer panels to absorb the energy was also determined. Based on the analysis of the obtained test results, it was proven that the core denoted as B, with inclination angle of the cell ribs $${{\varphi }_{x}=\varphi }_{y}=65^\circ$$ φ x = φ y = 65 ∘ , shows the highest compressive strength. It was determined that the dynamic load causes a very high overload in high-density fiber board face sheets. This results in damage to the sandwich panel surface and core structure. Cells of type B favorably minimize the differences in absorbed energy when using different face sheets and the energy value for low velocity impact. Taking into account the amount of absorbed energy, the most attractive is the panel with the D-type orthotropic core characterized by an inclination angle of the cell ribs $${\varphi }_{x}= 30^\circ , {\varphi }_{y}=60^\circ$$ φ x = 30 ∘ , φ y = 60 ∘ . The amount of energy absorbed by samples with high-density fiberboard face sheets increases significantly depending on the impactor's energy. For panels with face sheets manufactured from high-pressure laminate, the amount of energy absorbed decreases.

“…This allowed to absorb more energy, but at the same time increased the maximum force during the crushing process [19]. The filling is characterized by a similar behavior is the honeycomb, as multicell increases the amount of energy absorbed by additional planes inside the profile [11,16]. Another type of reinforcement of thin-walled structures is the use of foam filling [6].…”

This article presents the numerical tests of thin-walled compressed columns with a square cross-section. The crush efficiency indicators were determined using the finite element method (Abaqus) and neural networks of MLP. The models had a constant circular trigger, with a diameter of 32 mm. During dynamic analysis, the samples were loaded with 1700 J. The numerical models were filled with aluminum foam from 40 mm to 180 mm every 20 mm. The study presents the conclusions for the thin-walled models with crushable foam.

“…As aforementioned, the flexural waves emanate from the plate boundary and propagates towards the plate center [15]. Thanks for the development of innovative material technologies, kinds of composited light-weight structures were also investigated [16][17][18][19][20] under impact loads.…”

Defensive structure is important in transportation field for kinds of intentional or unintentional explosion. Structures subjected to unconfined and confined explosion will bear different blast loads and their dynamic responses are different. The present work focus on the dynamic response mechanism of steel plate under unconfined and confined blast loads through both numerical and experimental studies. In the experiment, Digital Image Correlation (DIC) technique was applied to record and analyze the dynamic response process of large-scale field blast test. The DIC measured curve and the numerical calculated curves agrees well in both the trends and the peak values. Then, the dynamic response mechanism of steel plate under unconfined blast (UB) load and confined blast (CB) load were compared and discussed. Results show that the dynamic response of plate can be divided into three phases under both UB and CB loads, while with different mechanism. In phase I, plastic hinge starts from the center and moves to the boundary in UB condition, while in case of CB, plastic hinge occurs close to the boundary and moves in the opposite direction. In phase II, two plastic hinge lines propagates towards each other, and a platform exists between the boundary and the central area remains undeformed in UB condition, while in CB condition, larger deformation in peripheral region rather than central area produces.
