Water-immersion softening mechanism of coal rock mass based on split Hopkinson pressure bar experiment

International Journal of Coal Science & Technology, 2022
The coal mining process is affected by various water sources such as groundwater and coal seam water injection. Understanding the dynamic mechanical parameters of water-immersed coal is helpful for coalmine safe production.

Design of a split Hopkinson pressure bar with partial lateral confinement [PDF]

Measurement Science and Technology, 2016
Abstract This paper presents the design of a modified split Hopkinson pressure bar (SHPB) where partial lateral confinement of the specimen is provided by the inertia of a fluid annulus contained in a long steel reservoir. In contrast to unconfined testing, or a constant cell pressure applied before axial loading, lateral restraint is

Targeting Orexin 2 Receptors in Idiopathic Hypersomnia and Narcolepsy: A Randomised Phase 1b Proof‐Of‐Concept Study of Alixorexton

Journal of Sleep Research, EarlyView.
Orexin 2 receptor agonists have demonstrated that targeting the orexin system may address symptoms of central disorders of hypersomnolence. Results of this phase 1 study support the phase 2 clinical evaluation of oral alixorexton in patients with IH, NT2 and NT1.

Signal Correction for the Split-Hopkinson Bar Testing of Soft Materials

Dynamics
The Split-Hopkinson pressure bar (SHPB) test is a commonly accepted experiment to investigate the material behavior under high strain rates. Due to the low impedance of soft materials, here, the test has to be performed with plastic bars instead of metal

Direct Measurement of Explosive Impulse From Contact to the Ultra‐Near Field

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 10, Page 1721-1736, October 2026.
ABSTRACT Measurement of impulse from explosive charges in contact and ultra‐near‐field regimes remains poorly characterised due to the short duration of loading, high strain rates, and the difficulty of obtaining direct momentum‐based measurements.

Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.

Paleomagnetism of the Scourie Dykes, Lewisian Foreland, NW Scotland: Constraints on Early Paleoproterozoic Paleogeography of Kenorland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Scourie dyke swarm in the Lewisian foreland of northwest Scotland provides key constraints on the Paleoproterozoic evolution of the North Atlantic craton. High‐precision U‐Pb geochronology identifies two distinct intrusive phases at ∼2.41–2.38 Ga and ∼2.00 Ga.

A NOTE ON DATA PROCESSING IN THE SPLIT HOPKINSON PRESSURE BAR TESTS [PDF]

Experimental Techniques, 1998
In this paper, a close-form relationship between the incident wave and the transmitted wave was deduced on the analysis of elastic wave propagation in SHPB tests for the elastic specimen. The relationship was applied to determine the time delay in data processing of SHPB tests in order to improve the accuracy of the measured stress-strain curve in the ...

Translating Circularity Into Strategy: A Governance Meta‐Capability Framework

Business Strategy and the Environment, Volume 35, Issue 6, Page 8746-8758, September 2026.
ABSTRACT Firms struggle to transition to circular economy (CE) models, often citing external barriers. Yet some firms succeed, whereas others fail: Why? We argue that success depends on a specific governance capability—a meta‐capability that allows firms to (1) sense and strategically reframe CE imperatives, (2) seize opportunities by aligning diverse ...
