When sufficient stress is applied, the response will be a change in shape. Ductile deformation is where things become interesting in terms of visual effects displayed in solid rock (see photo below). By Steven Earle from Physical Geology, CC BY 4.0Įlastic deformation of the crust would not be noticed. Most sedimentary rock types fit into this category. Material “C” undergoes significant plastic deformation before finally failing brittlely. The common igneous rock gabbro would fit here. Material “B” only elastically deforms before brittlely failing. The common metamorphic rock gneiss would fall into this category. Material “A” has relatively little deformation when undergoing large amounts of stress, before undergoing plastic deformation, and finally brittlely failing.
