Hypervelocity-Impact Damage of Ceramic Materials

Large-scale Molecular Simulations of Hypervelocity Impact of Materials

We describe the application of the ReaxFF reactive force field with short-range distance-dependent exponential inner wall corrections and the non-adiabatic electron Force Field (eFF) for studying the hypervelocity impact (HVI) effects on material properties. In particular, to understanding nonequilibrium energy/mass transfer, high strain/heat rate material decomposition, defects formation, plas...

Preservation of Organic Materials during Hypervelocity Impact Experiments

Introduction: The survivability of carbonaceous compounds during hypervelocity impacts has particular importance in exobiology, astrobiology, and origin of life studies. The delivery of biotic organics such as amino acids, which are found in meteorites [1], during impact is an important hypothesis for the source of life's early organics [2]. Furthermore, trapping or preservation of target organ...
