Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

steel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

Dynamic Support Characteristics of a Conical Hydrostatic Bearing Spindle and Their Effects on Surface Formation in Precision Grinding

Lubricants
The dynamic support characteristics of hydrostatic spindles have an important influence on precision grinding stability and surface quality. However, existing grinding surface-generation models usually prescribe spindle motion as a known input and rarely

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

steel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Stresses in Above‐Ground Storage Tanks Subjected to Flood‐Borne Debris Impact

Safety Science and Technology, EarlyView.
This study investigates the stresses induced in above‐ground storage tanks by flood‐borne debris, specifically steel pipes and wood poles. Findings demonstrate that debris impacts across the examined velocity range generate stresses within safe limits, not exceeding the yield stress threshold.

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

Structural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

Structural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

Whole‐Genome Sequencing and Resequencing of Hucho bleekeri Provides Insights into Genetic Mechanisms of Environmental Adaptation

Integrative Zoology, EarlyView.
A high‐quality chromosome‐level reference genome was constructed for Hucho bleekeri. Population structure and environmental adaptation of Hucho species were revealed by whole‐genome resequencing. ABSTRACT Salmonidae represents an important family in the study of genome evolution following genome duplication.
