When studying stress-strain behavior in tension, what is the reason for defining yield using the offset method (such as 0.2%, for instance)?

Define adiabatic shear fracture phenomenon, (typically seen during deformation at high strain rates)

Brittle fracture is more common in FCC metals compared to BCC or HCP.

List one advantage of torsion testing over tension testing.

Changing the strain rate of a tensile test typically has the following effect on behavior:
