Question 32
False,
Explanation: first crack is formed then there is propagation of the crack
Question 33
Correct answer: Brittle material,
Brittle material has steeper stress strain cruve because it undergo minimum deformation before failing
Question 32 Any fracture happen in two stages crack propagation and the next step is crack...
help with question 4 please. there are two samples given with two different pictures of each A material may fail in many ways; in a ductile or brittle mode; by creep or fatigue; by corrosion or stress corrosion; by hydrogen or liquid metal embrittlement; by slow tensile overload or by impact. An examination of the failure may tell you a lot about the material and the failure mode. In this course, you have learned (we trust) the correlations between structure-properties,...
