Influence of Strain Rate and Temperature on the Mechanical Behaviour of Armour Steels

ce/papers, Volume 9, Issue 2-3, Page 341-346, September 2026.
Abstract Armour steels are high‐strength alloys widely used in vehicles and protective structures due to their outstanding ballistic resistance. This work investigates the tensile behaviour of different Armox steels under the combined effects of high strain rate and elevated temperature.

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

Deep 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 ...

A new experimental methodology to assess the wall pressure generated by a high-voltage underwater Spark-generated bubble

Results in Physics, 2019
A new experimental methodology and test system is proposed to assess the wall pressure due to the high-voltage underwater Spark-generated bubble. In the methodology, a Hopkinson bar is used as the sensing element and the pressure signal is obtained based

Round-Robin test of split Hopkinson pressure bar

International Journal of Impact Engineering, 2019
Abstract A Round-Robin test using split Hopkinson pressure bars (SHPBs) has been conducted by four universities: Swinburne University of Technology (SUT), Australia; University of Sao Paulo (USP), Brazil; University of Cape Town (UCT), South Africa; and Nanyang Technological University (NTU), Singapore. Each university had different sets of SHPBs and

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

Deep 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.

Parametric characterization and error analysis of Hopkinson bar waveforms

Next Materials
The Hopkinson bar technique is an essential method for characterizing material dynamic properties. This study develops a parametric framework for stress waveform characterization, incorporating time-dependent markers (t0 to t3), amplitude-dependent ...

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

Limnology 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.

Advances in experimental assessment of dynamic tensile strength of concrete by the spalling technique

EPJ Web of Conferences, 2015
An experimental method to test concrete in dynamic tension by spalling with a Hopkinson bar as loading and measuring tool was developed in 1999. The dynamic strength of concrete specimen and strain rate were indirectly derived from an accurate data ...
