- (b) The difference between the theoretical and measured fracture strengths of brittle materials is explained by the presence of small flaws or cracks. In terms of these pre-existing flaws or cracks, briefly describe the occurring phenomena when a brittle material fractures in tension. (i) (ii) Explain why ductile materials do not fail in a brittle manner even though they have small flaws and crack present. If so, explain the process of ductile fracture of the materials.arrow_forwardA chemicals company is looking to optimise the materials selection for their synthesis vessel with safety being the key priority. The tank can be treated as a small thin-walled spherical pressure vessel and the engineers are considering a 'yield before break' design concept. Given that a crack of length will propagate by fast fracture when the stress intensity factor reaches the fracture toughness of the material select the correct materials property index relevant to this design criterion.
