Brittle Deformation When stress exceeds the elastic limit (strength) of a rock, the rock either bends or breaks.
Rocks that break into smaller pieces exhibit brittle deformation (bryttian = to shatter).
Brittle deformation occurs when stress breaks the chemical bonds that hold a material together.
When the cool candy bar is slowly bent, it will exhibit brittle deformation in the chocolate and ductile deformation in the caramel.
