“…Several studies were conducted on the development of numerical models that can be used in the validation of the macro-and meso-damage of FRPSS. These studies have investigated the fracture characteristics, [118][119][120] flexural properties, 60,121,122 and compression behavior 123 of such structures with two and threedimensional models. Farshidi et al 16 developed a 2D FEA model of a disbonded honeycomb-core sandwich structure using the crack surface displacement extrapolation method to investigate the energy release rate and mode-mixity of the panels.…”

The use of fibre-reinforced plastics (FRPs) in sandwich structures increased for various industrial applications thanks to their strength-to-weight ratio which provides designers with advanced options for modern structures. FRP Sandwich Structures (FRPSS) are often used in aerospace, biomedical, defence, and marine products, where their high structural performance is required to sustain complex in-service loads and withstand varying environmental conditions. Progressive degradation of FRPSS under such circumstances has been a subject of interest for researchers owing to safety requirements for products with FRP. This paper reviews the state-of-the-art of the mechanical behaviour of FRPSS subjected to various loading regimes. It highlights the variation in structural performance, viscoelastic properties, damage resistance, and sequence of environmental degradation of FRPSS. Numerical methods and damage algorithms used to predict failures are also presented to provide sufficient knowledge for the design of FRPSS. This review contributes to further research on characterizing the properties of FRPSS under quasi-static and dynamic loading conditions.

“…A commonly used bonded (tie) connection was used between the contacting surfaces of the corrugated core and also the surfaces of the facings and the core. [19,[51][52][53] Global interaction with hard contact was defined for all the normal behavior, and a friction coefficient was 0.1 for tangential behavior. [54][55][56][57][58][59] Due to the orthotropic properties of wood, the facings and core materials were assigned appropriate orientations following the global coordinate system (Figure 5).…”

Wooden sandwich panels with a corrugated core have not been the subject of scientific research so far. The anisotropic properties of the wood make it challenging to form corrugated shapes. Therefore, it is decided to determine the effect of geometric imperfections of the corrugated core made of wood veneers on the stiffness and strength of sandwich panels and the core elasticity modulus. The beams are manufactured in industrial conditions and subjected to three‐point bending. The research is carried out in the form of tests and numerical calculations. It is demonstrated that geometric imperfections of the core affect the stiffness and strength of sandwich panels. The modulus of elasticity can reach values lower by up to 37% and the strength by up to 24% compared with reference panels with an ideal, symmetrical core geometry. However, their average linear elasticity modulus (1449 MPa) indicates excellent construction properties. Under the tests, four stages of beam bending are revealed. The last stage means that panels can increase stiffness even after the core is destroyed. The corrugated core's modulus of elasticity is also determined.

“…Around 80% of corrugated cardboards are manufactured using a single-layer structure (Niskanen, 2011), bringing the study of the mechanical properties of single-layer corrugated cardboards in focus. Toward understanding the mechanical properties of single-layer corrugated cardboards, researchers have conducted both static and dynamic characteristic experiments and theoretical studies (Vacher et al, 2011;Peli nski et al 2022;Luong et al, 2021;Garbowski et al, 2021;Di Russo et al, 2023). On the other side, drop tests, as a commonly used method for testing the cushioning performance of corrugated cardboard, can simulate real transportation and storage conditions, thus providing results that are reliable in practical application environments (Wu et al, 2016;Shi et al, 2017;Fadiji et al, 2016a;Wang, 2009).…”

PurposeThe primary objective of this study is characterizing the anisotropic mechanical properties of corrugated cardboard and simultaneously simulating its drop cushioning dynamic effects under various drop conditions.Design/methodology/approachStatic and dynamic tests were conducted on corrugated cardboard to obtain adequate experimental data in different directions. An effective anisotropic constitutive model is introduced by developing the honeycomb materials model in ANSYS LS-Dyna, and an effective approach is established toward effectively determining the material parameters from the test data obtained. The model is validated by comparing simulation results with experimental data from five drop conditions, including bottom drop, front drop, side drop, 30° side drop and edge drop. Additionally, simulations are conducted to study the cushioning performance of the packaging by dropping the corrugated cardboard at different heights.FindingsThe study establishes a fast and effective approach to simulating the drop cushioning performance of corrugated cardboard under various drop conditions, which demonstrates good agreement with experimental data.Originality/valueThis approach is of value for packaging protection and provides guidance for stacking of packaging during transportation.
