Summary: In finite element analyses, composite laminates are often homogenised and modelled using beam and plate elements. However, these structural elements are inaccurate for laminates with distinct in-plane stiffnesses, such as sandwich structured composites. To address this issue, a multiscale layerwise beam model based on the Timoshenko-Ehrenfest beam theory is proposed, which captures the key deformation modes of bending and transverse shear. The model is implemented using Direct FE2, a versatile computational homogenisation scheme that also captures deformation mechanisms at the mesoscale. The proposed approach provides accurate macroscale responses and resolution to mesoscale deformations in significantly less computation time.

Summary: This study investigates the fracture behavior of sandwich structures with foam core slits using the phase-field method to simulate the complex fracture process. It is found that structures with resin-filled slits exhibit better fracture resistance and ductility. The study also examines the effects of the number of slits, slit spacing, and foam core density on load-carrying capacity and fracture resistance.

Summary: Composite Sandwich Panels (CSP) with AAC core showed improved insulation fire rating compared to CSP with FC core, with the best performance seen in FC CSP with a density of 1000 kg/m(3). AAC CSP also outperformed FC CSP with a density of 650 kg/m(3). Both materials can be utilized for composite sandwich panels with better thermal and mechanical performance.

Summary: This paper reviews the research on the applications, manufacturing, properties, and performance of sandwich structures with balsa wood cores. Balsa wood offers advantages such as environmental sustainability, low cost, excellent mechanical properties, and thermal insulation. However, challenges including global supply chain issues and limitations in processing techniques, as well as impact, blast, fire, and water durability, need to be addressed. The paper also discusses future research directions for balsa structural sandwich materials.

Summary: This paper investigates the mechanical behavior of folded timber sandwich structures developed using integral rotational press-fit joints. Experimental testing shows failures occurring at joint locations with maximum hogging moment, with bending and tensile as the main failure modes. A nonlinear model and simplified frame model are proposed to predict the FRP fracture modes.

Summary: Graded lattice sandwich structures (GLSSs) can achieve superior structural performances through continuously-varying lattice configurations and properties in space. This study introduces a design method using multiscale topology optimization, reducing computational burden and ensuring manufacturability. Numerical examples and bending tests demonstrate that GLSSs are stiffer and have larger natural frequencies compared to uniform lattice sandwich structures.

Summary: This paper presents a higher order laminate model with sub-lamination capability for simulating wave propagation within delaminated composite and sandwich beams. Each sub-laminate adopts cubic and quadratic through-thickness variation for axial and transverse displacement, respectively. The model can achieve the desired level of accuracy and computational efficiency by using a suitable sub-lamination scheme, and it also incorporates the effect of contact within delamination regions.

Summary: The paper proposes a novel design and fabrication strategy for producing architected structures as the core in composite sandwich structures, which can dissipate energy and exhibit structural recovery. The mechanical response and design parameters relationship of conical unit cells are investigated, showing that the structures with curved sidewalls can dissipate energy and recover from deformation. The study demonstrates that the buckling strength and post-buckling stability of these structures are influenced by geometric parameters, providing insights for their applications in engineering materials.

Summary: This article discusses the sequential design of experiments for multi-fidelity numerical simulators, proposing a new Bayesian strategy called maximal rate of stepwise uncertainty reduction (MR-SUR) which aims to maximize the ratio between expected reduction of uncertainty and simulation cost. The strategy unifies existing methods and provides a principled approach for developing new ones.
