Shape memory fixity
Webb11 apr. 2024 · The shape memory properties of SMPs can be quantified using the shape recovery ratio (R recovery) and shape fixity ratio (R fixity ). An ideal SMP would have R recovery = R fixity = 1, meaning it would maintain its temporary shape and fully recover its original shape during the recovery process.
