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: This paper investigates the dynamic mechanical properties and damage mechanisms of polypropylene fiber-reinforced cemented tailing backfill (PFRCTB) under different strain rate conditions. The results indicate that the strain rate enhancement effect of PFRCTB under dynamic loading is significant, and the presence of confining pressure significantly changes the stress-strain curve.

Summary: The bar properties necessary for bar impact tests were calibrated using the 1D method and 3D method, which were cross-verified for a maraging steel bar. The paper also considers the method of calibrating measured strain and presents a method of determining the impact velocity with reference to a reliably measured strain profile for a bar calibrated via the 1D method.

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: 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 study introduces a variation of the Hopkinson bar, called Direct Impact Tension Bar (DITB), which is well-suited for probing low-impedance materials at intermediate strain-rates. The DITB offers accurate force signals without detrimental oscillations, making it a reliable tool for studying strain-rate effects. Experimental results on polycarbonate specimens demonstrate the applicability of the DITB in dynamic tensile tests, providing high-quality data free from oscillations.

Summary: This study investigates the role of texture and anisotropy in the ballistic response of rolled magnesium alloys using a combined experimental-computational approach. Anisotropic deformation behavior arises from deformation mechanisms with disparate strength and strain hardening behavior, with low-strength extension twinning governing the initial anisotropic deformation and bulging of the plate. Experiments and simulations suggest that material orientation plays a crucial role in dictating eventual fracture and failure in strongly anisotropic metals under low to intermediate ballistic loading rates.
