C-SWARM | Center for Shock Wave-processing of Advanced Reactive Materials
Our goal is to predict the behavior of heterogeneous materials, specifically the dynamics of their shock induced chemo-thermo-mechanical transformations and resulting material properties. Our full system demonstration problem is to simulate the shock-induced synthesis of a nickel-aluminum composite in a Taylor impact experiment. Moreover, through the adaptive Exascale simulations, we aspire to predict conditions for synthesis of novel materials-by-design and provide prognoses of non-equilibrium structures that will form under shock wave processing. In particular, we plan to identify conditions under which we can synthesize cubic boron nitride (c-BN). c-BN is not found in nature and therefore can only be produced synthetically. The hardness of c-BN is inferior only to diamond, but its thermal and chemical stability is superior. Because of these properties, c-BN surpasses diamond in high temperature mechanical applications. Shock synthesis of c-BN enabled by Exascale predictive computations with V&V/UQ will be a significant scientific achievement.
