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