Momentum enhancement simulations for hypervelocity impacts on sandstone

• Generated material constants from test and literature data that capture the proper physics (pressure dependence, strain rate, strength of failed material, bulking) Performed hypervelocity impacts measured crater dimensions momentum enhancement. Checked with models provide right computations shape Abstrac t Two NASA missions will be launched in 2022 have spun renewed interest impact rocks metals. This paper is focused prediction enhancement effect, i.e. extra acquired by target due to ejecta flying off direction impactor. Predicting simulations has been elusive, probably because rarely well characterized. shows that, given a good knowledge properties and, adding two essential pieces (strength bulking after failure), computer can predictions for tests performed at Southwest Research Institute.
