Behaviour and design of composite beams subjected to negative bending and compression [PDF]

, 2012
This paper investigates the behaviour of steel–concrete composite beams subjected to the combined effectsof negative bending and axial compression. For this study, six full-scale tests were conducted on compositebeams subjected to negative moment while ...

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures [PDF]

, 1988
A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in ...

Coral Reef Carbonate Chemistry Variability at Different Functional Scales

Frontiers in Marine Science, 2018
There is a growing recognition for the need to understand how seawater carbonate chemistry over coral reef environments will change in a high-CO2 world to better assess the impacts of ocean acidification on these valuable ecosystems.

Luminosity Loss due to Beam Distortion and the Beam-Beam Instability [PDF]

Proceedings of the 2005 Particle Accelerator Conference, 2006
In a linear collider, sources of emittance dilution such as transverse wakefields or dispersive errors will couple the vertical phase space to the longitudinal position within the beam (the so-called ‘banana effect’). When the Intersection Point (IP) disruption parameter is large, these beam distortions will be amplified by a single bunch kink ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

Advanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Prediction of Surface Topography Parameters in Direct Laser Interference Patterning of Stainless Steel Using Infrared Monitoring and Convolutional Neural Networks

Advanced Engineering Materials, EarlyView.
This study presents an infrared monitoring approach for direct laser interference patterning (DLIP) combined with a convolutional neural network (CNN). Thermal emission data captured during structuring are used to predict surface topography parameters.
