C-Specimen Fracture Toughness Testing: Sign into or create your free personal account Sign in via Shibboleth What is Shibboleth? In case 1, fracture occurs with no previous significant plasticity, in case 2 some plasticity occurs prior to fracture, while in case 3 a pop-in occurs, followed by some plasticity prior to final fracture.
