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

open access: yesExperimental 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 ...

The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 3, Page 829-842, September 2026.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 3, Page 869-882, September 2026.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Decoupling of dissolved iron and iron‐binding humic‐like substances along the West Antarctic Peninsula

open access: yesLimnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract The chemical speciation of iron (Fe) has important ramifications for the stabilization, transport, and bioavailability of this critical nutrient. Organic ligands mediate dissolved Fe biogeochemistry such that ligand concentration and molecular composition help shape dissolved Fe distributions.

Impact Behavior of Recycled Aggregate Concrete Based on Split Hopkinson Pressure Bar Tests

open access: yesAdvances in Materials Science and Engineering, 2013
This paper presents the experimental results of recycled aggregate concrete (RAC) specimens prepared with five different amounts of recycled coarse aggregate (RCA) (i.e., 0, 25%, 50%, 75%, and 100%) subjected to impact loading based on split Hopkinson ...

A Comparison of Classical Constitutive Models for High‐Entropy Alloy Behavior: Effects of Medium Strain Rates and Temperature on Plastic Flow

open access: yesMaterials Genome Engineering Advances, Volume 4, Issue 3, August 2026.
Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...

Spatial Variability and Drivers of Salt Marsh Cliff Erosion in the Dutch Wadden Sea: From Observation to Simulation

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Lateral erosion of salt marshes via cliff retreat is a primary cause of global marsh loss, driven by interactions between hydrodynamics, sediment, and vegetation. While previous studies show a linear relationship between wave power and cliff retreat, models based on this relationship are largely unvalidated for short‐term (sub‐yearly) and ...
