Experiments reveal how strain rate affects the failure behaviors of sandstone, suggesting key insights into energy damage mechanisms.

Strain rate significantly influences the mechanical behavior of sandstone, with higher rates leading to increased peak stress and elastic modulus.
Energy damage characteristics indicate that high strain rates result in brittle failure and fragmentation, while low rates favor shape integrity.
The study employs mechanical experiments to explore the relationship between strain rate, energy dissipation, and damage in sandstone rock samples.
Findings provide a theoretical basis for assessing surrounding rock damage and early warning mechanisms under mine roof pressure.
