    Simulations elucidate metal strength

    Due to severe limits on accessible length and time scales, it was long thought impossible or even unthinkable to use direct atomistic simulations to predict metal strength. In a first-of-its-kind series of computer simulations focused on metal tantalum, a team of Livermore scientists predicted that metal plasticity meets its limits when reaching certain critical conditions of straining.
