The true stress-strain curve for a material can be represented with the linear, rigid strain hardening model with Y=100+50 (MPa) in compression and tension. A 25 mm by 25 mm by 50 mm tall block is open die forged at room temperature. Friction can be assumed to be zero, and you must include redundant work in your analysis if it is applicable. Find: HT Q, a) The pressure on the die when the block is forged to a height of 40 mm 3 2 1 A 01 5 10 b) The required force output for the forging machine to forge the block to a height of 40 mm (a) 6 - 6 = 17| 11-2 7
