Abstract
Molecular dynamics studies were carried out to simulate the growth of a single {−1012} tensile twin and two adjacent {−1012} twins. For the single twin, transverse propagation is faster than thickening. For the two adjacent twins, one twin’s growth is predominant over the other when they are 45° to each other. These phenomena are attributed to the interaction of stress field around PB interfaces and twinning planes. The asymmetric stress distribution leads to the twins’ asymmetric growth.
