Shape recovery process

Definition

The shape recovery process refers to the ability of certain materials to return to their original shape after being deformed by an external force. This capability is essential in the development of synthetic self-healing materials, as it allows them to restore functionality and integrity after sustaining damage, mimicking biological healing processes found in nature.
