Forming Capability Differences due to rolling diff. (R0, R45, R90)
Forming Capability Differences due to rolling diff. (R0, R45, R90)
(OP)
My company has ran into a job using AL2024 T42 (0.050" thickness) which wrinkle constantly in the middle( part look like a saddle). The finite element analysis result shows if I can increasing the material's R0, R45 and R90 property to be greater than one then I can solve this problem. Are there good literatures I can learn more about what are R0, R45, R90 and their impact to forming capability? Is there any mill house can deliver special property requirment like these?

for a different alloy, suggests that the coefficients may all go above unity at high temperature. How do you feel about elevated temperature forming?
