Preview Abstract
The molecular dynamics simulation model of aluminum with intersecting cracks was set up. The crack propagation behavior of aluminum with intersecting cracks was studied by using the embedded atom method and the rate loading molecular dynamics method. The effects of the loading rate and angle of crack on the crack propagation behavior of aluminum with intersecting cracks were investigated. The research results show that with the increase of loading speed, angle crack extension has a positive role in promoting. As the angle of crack increases, the angle crack is more difficult to expand and the extend path is more complicated.
