Rocks often experience very rapid loading in both natural and engineering settings, such as during earthquakes, asteroid impacts, and mining activities. While advanced exper- iments can help us understand how rocks respond to these loading, they are expensive and time-consuming. Here, we developed a…
Granite is a typical anisotropic and brittle rock, which may experience uniaxial, biaxial, or triaxial stress states in geological structures. It may be subject to extreme dynamic loads, such as earthquakes, planetary impacts, and underground explosions. However, the deformation and damage of granite associated…
Understanding the dynamic behavior of concrete under high pressure and high strain rates is critical for designing resilient materials in civil and defense applications. Traditional phenomenological constitutive models, which rely on empirical laws, often conflate the effects of various mechanisms—such as intrinsic material properties…
Diamond is widely used in high-power laser experiments due to its optical transparency and high strength under compression. The latter of these two properties is not well understood. Previous work indicated conflicting results; high strength maintained to 800GPa (Bradley, 2009), complete loss of strength…
The performance of concrete materials under high pressures and high strain rate loading is critical to their use in protective structures. In this work, we investigated damage in mortar samples subjected to high-velocity projectile impacts to assess performance and deformation mechanisms. Projectile impact tests…
Accumulation of microplastic defects generated through high cycle elastic fatigue loading results in microstructure, especially porosity, states that vary significantly from the pristine materials typically investigated in shock studies. In order to probe the effects of these microstructural changes, specimens of α Fe and…
