hep with question 3 please
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, - applications. This leads to material selection. However, the engineer has...
