Robust atomistic calculation of dislocation line tension

The line tension Gamma of a dislocation is an important and fundamental property ubiquitous to continuum scale models of metal plasticity. However, the precise value of Gamma in a given material has proven difficult to assess, with literature values encompassing a wide range. Here results from a multiscale simulation and robust analysis of the dislocation line tension, for dislocation bow-out between pinning points, are presented for two...
