Question

Identify the stress strain in the flange portion of a partially drawn cylindrical cup when deep drawing without a blank holder

• A. tensile in all three directions
• B. no stress in the flange at all, because there is no blank holder
• C. tensile stress in one direction and compressive stress in other direction
• D. tensile in two directions and compressive in third direction

Answer 1

The correct option is B no stress in the flange at all, because there is no blank holder

Since there is no blank holder. Hence no stress will be developed.
