| Abstract Scope |
Geomaterials such as sands, rocks, and concrete experience high strain rates and pressures during projectile impacts, mining activities, and planetary impacts. Developing a quantitative understanding of the material deformation mechanisms activated during such events is critical for building predictive analytical and constitutive models. Here, we discuss the marriage of advanced experiments involving in-situ X-ray imaging and diffraction diagnostics with advanced mesoscale models initialized with the exact microstructures used in experiments. We discuss efforts to use this combined experimental-numerical approach to quantify fundamental mechanisms in these materials during high-strain-rate compaction, such as pore collapse, and the effects of material properties and texture on the development of compaction waves, pressure fields, and temperature fields. We also discuss efforts to use the experimental-numerical approach more broadly to quantify deformation mechanisms of rocks in high-pressure, low-strain-rate settings. |
