Molecular dynamics simulations of the effects of annealing on the micro residual stress induced by vacancy defects in aluminum crystal

•Maximum range of residual stress change is approximately linear with void radius.•Atomic stress near void of different sizes changes differently during annealing.•Atomic distributions near void are more uniform and regular after annealing.•Different sizes of voids affect atomic potential energy and...
