A molecular dynamics simulation was performed to study the localization of regions with excess atomic volume in bcc iron single crystals with variously oriented incipient edge cracks under uniaxial tension at room temperature. It is found that a regi

The paper presents a molecular dynamics study on the propagation of an intrinsic stacking fault in a copper crystallite under tension. The study shows that the defect moves via the formation of four successive structural configurations in two adjacen
