Healing of Nanocracks by Disclinations

We present a new mechanism—discovered using molecular dynamics simulations—that leads to complete healing of nanocracks. This mechanism relies on the generation of crystal defects known as disclinations by migrating grain boundaries. Crack healing by disclinations does not require any compressive lo...
