“…It has been studied by many researchers in previous years by subjecting PUF sandwich composites to axial loading. Different Finite Element (FE) models and experiments have been conducted to study the buckling behavior and different failure modes in this previous research . Boccaccio et al analyzed the buckling response of PUF‐based sandwich composites subjected to edgewise compression.…”

Sandwich composites with a polyurethane foam (PUF) core have become a versatile set of materials with applications ranging from basic construction elements to advanced engineering materials. This diverse range of applications has provided these sandwich materials with a distinctive position in today's engineering world. This review focuses on the broad research that has been carried out on PUF core‐based sandwich composites over the years—especially in the last decade. Thorough details have been presented focusing on basic PUF core sandwich structures, advanced PUF core sandwich composites with different kinds of reinforcements and complex structures such as hybrid sandwich panels. All the research presented here has been categorized carefully, such as the types of materials used in various studies, the types of reinforcements and testing techniques used, including mechanical, electrical, dynamic, thermal and acoustic methods etc. Comparisons have also been made based on similar materials, similar testing procedures and similar application areas. Research areas have been highlighted by giving a deep insight into the most promising research, manufacturing techniques and improvement procedures. Major consumption areas and application sectors for PUF core sandwich composites have also been discussed in this review. Finally, conclusions have been made based on the results found from a literature investigation.

Various fatigue failure modes (i.e., cracking position and orientation with respect to a weld) can develop in welded rib to deck connections in orthotropic bridge deck structures. After demonstrating its effectiveness in correlating fatigue test data covering different failure modes, the master S-N curve method was then adopted in this study for determining the critical failure mode in welded U-rib to deck connections. These include considerations of additional failure modes potentially present in double-sided welds between U-rib and deck versus the traditional single-sided weld design. The effects of weld penetrations and test loading conditions on failure mode development have been quantitatively established by means of the master S-N curve method.

This paper presents the experimental and numerical analysis of a composite deck consisting of steel core, glass fiber reinforced polymer layer and a concrete slab. A finite element approach is proposed to predict the behavior of the composite deck. In order to demonstrate the efficiency of the composite deck, a reinforced concrete deck with identical ultimate load capacity is designed. The mechanical properties and geometrical configurations of constituent parts of composite deck are modified and the resultant effects are evaluated and discussed thoroughly. The results show that the proposed composite deck with a low thickness, low weight and suitable deformability is appropriate for prefabrication when compared to conventional deck with the same ultimate load capacity. The material properties can be modified to improve ultimate load capacity of the composite deck and the strength-to-weight ratio of the deck is increased by changing the steel material to aluminum. The ultimate load capacity is enhanced by changing the composite deck cross section.
