Comparing the failure of different materials

Описание к видео Comparing the failure of different materials

Fracture is the separation of a body into 2 or more pieces due to stress. Fracture occurs differently in different materials! In some cases, it might shatter into many pieces, while in others it might break into just two. In some cases, the fracture occurs via spontaneous crack propagation, while in others stress must be continuously applied to continue crack propagation. Some materials will deform first, others tolerate no strain. Flaws, like surface or internal cracks can drastically change the probability of fracture and failure. We show this with some examples of ceramics, plastics, and metals.
