Brittle and plastic deformation

WebThe elastic strain energy can be recovered, so if the deformation remains within the elastic limit, then all of the strain energy can be recovered. Strain energy is calculated as: ... Since a ductile material can withstand much more plastic strain than a brittle material, a ductile material will therefore have a higher modulus of toughness than ... Web4 BRITTLE VS. DUCTILE ROCKSE?? Ask students, “ Can you predict what will happen if you were to apply stress to it?” ANSWER: Accept all answers but encourage students to use terms like stress, strain, elastic and brittle deformation in their responses. c) Apply bending stress to the ends of the candy bar. This time it will bend easily by ductile (plastic)

A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy prior to fracture, even those of high strength. Breaking is often accompanied by a sharp snapping sound.
