Research on Rolling-Cut Double-Side Shear in Kinetics

, 2010
A simplified model based on linkage mechanism was set up through analysis of space shear mechanism and kinetic theory of new-type rolling cut double-side shear, complex and matrix has been developed for establishing the kinetic model of linkage mechanism,

Investigating the Contact Responses of the Roller Cavity Surfaces in the Compressor Blade Rolling Process

Advances in Materials Science and Engineering, 2020
The investigation of the contact responses is the key for evaluating the local wear of dies in the plastic forming process. This paper investigated the contact load distributions and evolutions of the roller cavities in the compressor blade rolling ...

Optimizing Lumber Densification for Mitigating Rolling Shear Failure in Cross-Laminated Timber (CLT)

Construction Materials
Rolling shear in cross-laminated timber (CLT) has been identified as the governing factor influencing design value. Likewise, densification has been found to be an effective method of enhancing the rolling shear strength of lumber and in turn, CLT.

Effect of Stacking Fault Energy on Microstructure and Texture Evolution during the Rolling of Non-Equiatomic CrMnFeCoNi High-Entropy Alloys

Crystals, 2020
The evolution of microstructure and texture in three non-equiatomic CrMnFeCoNi high-entropy alloys (HEAs) with varying stacking fault energy (SFE) has been studied in up to 90% rolling reductions at both room and cryogenic temperature.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Microstructural characteristics of magnesium alloy sheets subjected to high-speed rolling and their rolling temperature dependence

Journal of Materials Research and Technology, 2019
Microstructural and textural variations of an AZ31 Mg alloy during its high-speed rolling (HSR) and their dependence on the rolling temperature are investigated by performing HSR at temperatures of 300 °C, 350 °C, and 400 °C at a rolling speed of 470 m ...

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight

A shear stress micromodel of urinary tract infection by the Escherichia coli producing Dr adhesin.

PLoS Pathogens, 2020
In this study, we established a dynamic micromodel of urinary tract infection to analyze the impact of UT-segment-specific urinary outflow on the persistence of E. coli colonization. We found that the adherence of Dr+ E.
