Effects of interatomic potential on fracture behaviour in single- and bicrystalline tungsten
In the present work, we have evaluated the performance of different embedded atom method (EAM) andsecond-nearest neighbour modified embedded atom method (2NN-MEAM) potentials based on their predictivecapabilities for modelling fracture in single- and bicrystalline tungsten. As part of the study, a new 2NN-MEAMwas fitted with emphasis on reproducing surface, unstable stacking fault and twinning ene
