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

Materials Genome Engineering Advances, EarlyView.
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 ...

Characterisation of dynamic behaviour of alumina ceramics: evaluation of stress uniformity

AIP Advances, 2015
Accurate characterisation of dynamic behaviour of ceramics requires the reliable split-Hopkinson pressure bar (SHPB) technique and the condition of uniaxial homogeneous specimen deformation.

Shear Fault Formation in Granite Under High and Transient Co‐Seismic Strain Rates Unveiled by Ultra‐Fast X‐Ray Imaging

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract During an earthquake a dynamic rupture propagates, causing fractures and permanent damage that modify the mechanical properties of the fault and its surroundings. Reciprocally, the energy dissipated by the mechanical transformation of the fault rock has a direct feedback on the dynamics of the seismic rupture.

Strain hardening and shock mitigation response of polyurethane under high strain rates

AIP Advances, 2021
Polyurethane is a promising candidate for the potting of embedded electronics due to its shock absorbing properties. This paper discusses the less known strain hardening and shock mitigation properties of 4,4′-methylenediphenyl diisocyanate based ...

Dynamic tensile strength and fracture evolution of characteristic shale with bedding and hole using linear regression theory

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 426-445, June 2026.
The spiral conical perforations generated during methane in situ explosion fracturing operations lead to tensile fracture propagation in shale reservoirs being governed by the combined effects of impact pressure, bedding, and aperture under explosive loading. Using multiple regression analysis and digital image correlation technology, the mechanisms of

Bioinspired Regenerative Lignification Enables Ultra‐Hard and Sustainable Bamboo Structural Materials

Exploration, Volume 6, Issue 3, June 2026.
Developing strong and sustainable materials is essential for reducing reliance on metals and lowering carbon emissions. Inspired by how plants naturally harden their cell walls, we created a rapid process that transforms bamboo into an ultra‐hard structural material by rebuilding lignin‐like networks within its structure.

Experimental Investigations on the Energy Absorption of Aluminum TPMS Structures Under Dynamic Loading

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Triply periodic minimal surfaces (TPMS) constitute a prominent class of cellular structures and have gained considerable attention in current research. These structures are genus‐infinite surfaces with zero mean curvature, which prevents self‐intersection. They also exhibit periodicity in all three spatial directions and exhibit enhanced multi‐

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

Experimental investigation on dynamic compressive properties of SHCC after freeze-thaw cycles

Journal of Materials Research and Technology, 2023
In this paper, the split Hopkinson pressure bar (SHPB) test was used to investigate the variation of dynamic compressive properties of SHCC with various freeze-thaw (FT) cycles and strain rates.
