What are the two experimental procedures for determining if a sheet metal part of a specific material can be made by SPIF?
What are the two experimental procedures for determining if a sheet metal part of a specific material can be made by SPIF?
- Principal strain-space (e1, e2) and conventional circle-grid analysis
- Conventional circle-grid analysis and maximum drawing angle cmax (correct)
- None of the above
- Maximum drawing angle cmax and principal strain-space (e1, e2)
What is the theoretical background behind using cmax as a criterion of failure?
What is the theoretical background behind using cmax as a criterion of failure?
- It is related to the principal strain-space (e1, e2)
- There is no theoretical background behind using cmax as a criterion of failure (correct)
- It is related to the thickness of the sheet t0
- It is related to the conventional circle-grid analysis

What is one of the aims of the present paper?
- To introduce a new experimental procedure
- To provide the missing background by relating the two experimental procedures (correct)
- To compare the two experimental procedures
- To criticize the two experimental procedures
