WebBrittle deformation: Irreversible strain when rocks break in pieces in response to stress. Any material that breaks into pieces exhibits brittle behavior. Ductile deformation: when rocks flow or bend in response to stress (ex. clay). This strain is also irreversible.

Since it is rigid and brittle, when … WebJul 18, 2013 · Ductile rocks behave plastically and commonly become folded in response to stress. Folding can happen in the shallow crust if the stress is slow and steady and gives the rock enough time to gradually bend. If the stress is applied too quickly, rocks in the shallow crust will behave as brittle solids and break.
