Figure 9.2. 1: Different materials deform differently when stress is applied. Material A has relatively little deformation when undergoing large amounts of stress, before undergoing plastic deformation, and finally brittle failure. Material B only elastically deforms before brittle failure.

Brittle deformation brings about fractures and faults. The two main types of faults are dip-slip (the fault plane is inclined to the horizontal) and strike-slip (the fault plane is ...
WebThis relationship is known as Hooke's law. Plastic deformation takes place when a rock, mineral, or other substance is stressed beyond its elastic limit ( Fig. 1 ). Plastic deformation is that deformation that produces a permanent change in the shape of a solid without that solid having failed by fracturing.
