While contribution of physics to model fracture of materials is significant, the “reversed” process of healing is hardly investigated. Inspired by fracture healing that occurs as a self-repair process in nature, e.g. in bone, we computationally study the conditions under which a material can repair itself. In our model the material around a fracture is assumed mechano-responsive: it processes the information of i) local stiffness and ii) local strain and responds by local stiffening. Depending on how information i) and ii) is processed, healing evolves via fundamentally different paths.
