Studying the pressure scaling of flow stress in Ta using molecular dynamics simulations

Molecular dynamics forms a key simulation technique in used in the construction of multiscale strength models. We present molecular dynamics simulations of the isochoric deformation of single crystal tantalum using our in-house developed MEAM potential. We compare the pressure dependence of the calculated flow stress with that of the calculated elastic moduli and the predictions of a number of commonly used isotropic strength models.
