High-strain-rate mechanical response of HTPE propellant under SHPB impact loading

open access: yesAIP Advances, 2021
The high-strain-rate dynamic response of a hydroxyl-terminated polyether (HTPE) propellant during impact loading is essential for assessing the structural reliability and impact safety of HTPE propellant.

Identification of non-homogeneous stress fields in dynamic experiments with a non parametric method [PDF]

open access: yes, 2010
International audienceStress and strain fields are generally assumed homogeneous in high strain rate experiments. Therefore, only mean stress and strain are measured. However, this assumption is not valid for soft materials and/or very high strain rates.

Highly Oriented Bio‐Mimetic Hydrogels by Calendering

open access: yesAdvanced Science, Volume 12, Issue 30, August 14, 2025.
A facile and scalable organogel‐assisted calendering strategy is proposed to prepare bio‐mimetic anisotropic polyvinyl alcohol (PVA) hydrogels. By employing a combination of shearing and annealing during calendering, PVA chains are aligned in the calendering direction, while the compression in thickness facilitates the formation of a nacre‐like ...

Study on Energy Evolution Law of Rocks With Different Lithologies and Sizes

open access: yesEnergy Science &Engineering, Volume 13, Issue 8, Page 4199-4210, August 2025.
ABSTRACT Investigating the actual patterns of energy accumulation and release in roof rock, particularly with varying stiffnesses in mining environments, is crucial. By conducting cyclic loading and unloading tests on rock samples of different lithologies, different sizes, and consistent stiffness, how lithology, size, and stiffness affect the ...

Investigating the Dynamic Behavior of Gabbro Specimens With Echelon Joints

open access: yesEnergy Science &Engineering, Volume 13, Issue 7, Page 3620-3630, July 2025.
Investigating the dynamic behavior of rock specimens with echelon joints based on SHPB tests. ABSTRACT To reveal the influence of dynamic load on the dynamic damage behavior of jointed rock masses, split Hopkinson pressure bar (SHPB) system was employed to test platy gabbro samples with joint angles of 15°, 30°, 45°, 65°, and 75° at an impact pressure ...
