Give some serious concerns (pitfalls) regarding strain analysis.
What will be an ideal response?
Ans: • There must be no viscosity contrast (see Question 3.3)
• There may be an initial fabric that must be accounted for, which is not always easy (Question 3.4).
• Strain must be homogeneous at the scale of data collection (a prerequisite) – a condition that is rarely fulfilled to the full extent.
• Measuring the orientation of section(s) relative to principal strain axes involves an uncertainty. In most cases, two-dimensional strain analyses is done in the section to represent one of the principal strain planes.
