Abstract:
This cutting-edge review highlights the fundamentals, design, and manufacturing strategies used for sandwich composites. Sandwich composite structures have the advantages of light weight, high strength, impact resistance, stability, and other superior features for advanced applications. In this regard, different core materials have been used in the sandwich composite structures, such as cellular polymer foam, metallic foam, honeycomb, balsa, tubular, and other core geometries. Among these, honeycomb sandwich composite materials have been effectively applied in space engineering, marine enginee

It is widely understood that moisture can have a detrimental effect on the strength of composite structures. Traditional analysis often focuses on the effects to solid laminates or on the facesheets of composite sandwich structures. However, this focus is often not sufficient to ensure material strength and performance. It has been found that moisture effects on sandwich structures can also have a detrimental effect on secondary failure modes such as shear crimping and facesheet wrinkling, and that these effects can be significant, especially at temperature. A proper assessment of moisture eff

Abstract:
The purpose of this study is to evaluate the dynamic response of fiber-reinforced polymer (FRP) composite sandwich panels subjected to typical barge impact masses and velocities to develop force time histories that can be used in controlled experimental testing. Dynamic analyses were performed on FRP composite sandwich panels using the finite element method software Abaqus/Explicit. The “traction-separation” law in the Abaqus software is used to define the cohesive surface interaction properties to evaluate the damage between FRP composite laminate layers as well as the core separation within

AXIAL COMPRESSION BEHAVIOR OF DOUBLE-SKIN COMPOSITE SHEAR WALL WITH T-STIFFENER AND HEADED STUD CONNECTORS. The Hong Kong Institute of Steel Construction, 2025. https://doi.org/10.18057/ijasc.2025.21.2.1.

Abstract:
Double-skin composite shear walls (DSCSWs) offer high strength and improve construction processes in tall structures, offshore constructions, and nuclear power plants. This paper investigates the compressive performance of DSCSWs, which consist of concrete sandwiched between two external steel faceplates and bonded with connectors at regular intervals. Three-dimensional finite element (FE) modeling is established and verified against five axial compression test specimens to predict the ultimate compressive capacity and failure modes of DSCSWs with bolts, head studs, and T-stiffener connectors.
