Simulation of Dislocations in Metals - 2 of 2
As the raft is stressed with the slider, dislocations move into and out of the grains and their boundaries. Defects can be seen zipping through the raft as the raft is stressed. Defects move one bubble at a time, gradually displacing the defect. The non-directional attraction between soap bubbles models the non-directional attraction between metal atoms, and a close-packed array is formed.
