Reliability analysis of composite sandwich structure for fuselage skin based on surrogate model
Xibei Gongye Daxue Xuebao, 2022 Composite structures are characterized by multiple source uncertainties in mechanical properties, geometric dimension, etc., and multiple failure modes, which bring challenges to their design and application.

Finite Element Analysis of Sandwich Structures [PDF]
, 1991 Sandwich construction may be defined as a three-layer type of construction where a relatively weak, low-density core material supports and stabilizes thin layers of high strength face material Its typical features, namely high strength-thin and low strength-thick materials, interfaces, bonding and load transfer suggest that each of the layers will ...

Optimization of load introduction points in sandwich structures with additively manufactured cores
Design Science, 2020 This paper presents how numerical optimization methods, like topology optimization, and new design possibilities through additive manufacturing (AM) can be used for structural improvements of the load introduction points in sandwich structures.

Bending analysis of sandwich panel composite with a re-entrant lattice core using zig-zag theory
Scientific Reports, 2022 The sandwich panel structures have been widely used in many industrial applications because of their high mechanical properties. The middle layer of these structures is very important factor in controlling and enhancing their mechanical performance under

Structural behaviour of folded timber sandwich structures
Thin-Walled Structures, 2021 This paper aims to characterise the mechanical behaviour of folded timber sandwich structures developed using integral rotational press-fit (RPF) joints. Six folded arches are tested to failure, under three load cases designed to induce different sagging and hogging conditions at internal joints.

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Enhanced the impact resistance by gradient face-sheet design of a sandwich structure
Journal of Materials Research and Technology, 2023 Sandwich structure has been designed to reduce the impact damage of the stress waves. However, the existing work focuses on the optimization of sandwich cores while the face-sheet structure is seldom improved.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.
