Mechanical Characterization of Compact Basalt by Using SHPB Device [PDF]

The 18th International Conference on Experimental Mechanics, 2018
In the present work, dynamic stress-strain response of compact basalt is tested under high loading rates using 38 mm split Hopkinson pressure bar (SHPB) device. The physical and static mechanical properties of compact basalt, e.g., density, specific gravity, static compressive strength and elastic modulus values are also determined.

Stress analysis of crack characteristic of anthracite under dynamic loading

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 56-65, March 2026.
In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack characteristic stress threshold considering the strain rate effect is established. Then, the rationality of crack characteristic stress under

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.
