Regarding the fracture mechanism of metals, polymers and ceramics (a) Explain why FCC metals show a ductile fracture even at low temperatures while BCC metals do not. (b) What is crazing? What can you say about the Poisson’s ratio of the crazed material? (c) Generally, in ceramics, intergranular fracture is preferred to cleavage fracture; however, in metals, transgranular fracture is the preferred mechanism for brittle failure. Why? Use a physical reason supported with an equation in your answer.
