Return-Point Memory (IMAGE)
Caption
Return-point memory relies on the alternating of direction of the external force, or “driving,” much like a combination lock relies on the dial being turned both clockwise and counterclockwise. The mathematical theorems for return-point memory suggest that materials cannot store a sequence of previous deformations if the driving is only in one direction, or asymmetrical. However, a team of researchers found the exact conditions under which this this type of material memory is possible.
