Previous 2D (plane strain) predictions on transonic twinning were verified by means of new free three-dimensional atomistic simulations by using the molecular dynamics technique and via analyses of acoustic emission sources in body-centered cubic iron crystal with an embedded central through-crack (001)[110] loaded in mode I. Molecular dynamics simulations in three-dimensions were completed by stress calculations on the atomistic and continuum level to analyze shielding or anti-shielding effect caused by the twins.
