Summary: Dynamic failure experiments were conducted on coal samples under dynamic load in a triaxial Split-Hopkinson pressure bar test system to study the dynamic characteristics of coal in a multi-axial pre-stress state. The experiments showed that the 3D pre-stress state significantly affects the dynamic failure of coal. The dynamic initial stress of coal increases linearly with strain, then grows at a reduced rate until the peak strength, and the mechanical curve rebounds notably. The dynamic strength factors of coal vary significantly with the increase of confining pressure.

Summary: The uniaxial compression behavior of building sandstone at high strain rates is investigated using dynamic and static compression tests. It is found that the static compression strength of flattened cylinders is 50% higher than that of standard cylinders. The study also explores the relationship between strain rate and fracture damage, and analyzes the correlations between dynamic strength, strain rate, and dynamic modulus based on experimental results.

Summary: This paper proposed an electromagnetic loading process with high-speed impact using Al-4.2% Cu alloy bars for experiments. The adiabatic shearing mechanism dominated the deformation process, leading to the formation of adiabatic shear bands (ASBs) as significant microstructure characteristics. The rotational dynamic recrystallization mechanism contributed to the formation of recrystallization grains with large angle grain boundaries.

Summary: This paper presents an innovative technique for measuring the bond stress-slip relationships during dynamic pull-out using a tensile split Hopkinson bar and a near-to-full-scale beam-end specimen. The complex wave propagation behavior during impact is characterized and two methods for separating the longitudinal stress waves are employed. The method is considered suitable for evaluating the dynamic bond stress-slip relationship.

Summary: Low-iron ultra-clear float glass (LIFG) has become popular in landmark and large-scale buildings for its aesthetic characteristics. This paper investigates the dynamic mechanical properties of LIFG for blast resistance design by conducting quasi-static and dynamic tests. The results show that the dynamic compressive and tensile strengths of LIFG are strain-rate dependent, with the tensile strength being more sensitive to strain rate. The strain rate effect does not significantly affect the Young's modulus of LIFG.

Summary: In this study, the adiabatic shearing of single crystals was achieved by using large-sized columnar crystalline pure copper specimens prepared by directional solidification and a hat-shaped sample design. The flow stress was found to increase with increasing strain rate, and the dominant deformation mechanism at high strain rates was slipping rather than twinning. The microstructure of the sheared zone showed the transformation from large-sized dislocation cells to elongated dislocation cells and the occurrence of equiaxed recrystallized grains. This instantaneous grain refinement was attributed to the dynamic recrystallization of pure copper under adiabatic shearing conditions.

Summary: The research utilized SHPB to test the high strain rate compressive behavior of cemented paste backfill (CPB). The results showed that increasing the cement content, tailings content, and curing age can improve the dynamic compressive strength and elastic modulus of CPB. Under dynamic loading, higher strain rates lead to larger increasing times of dynamic compressive strength, and there is an exponential correlation between dynamic compressive strength of CPB and strain rate.

Summary: In this study, the microstructural characterization and mechanical behavior of the extruded ZK61 alloy under dynamic and quasi-static loading at 623 K were investigated. It was found that an adiabatic shear band (ASB) composed of ultra-fine grains was formed under dynamic loading, while shear deformation occurred in an area with equiaxed grains under quasi-static loading. The stress-strain curve of dynamic loading showed high yield stress and long working-hardening stage, while the strain-hardening and thermal-softening in quasi-static curves reached a dynamic balance.
