Forming limit diagram in PAM STAMP
Forming limit diagram in PAM STAMP
(OP)
Hello everybody,
I'm trying to understand how PAM STAMP generates the FLD with "autoKeeler" option.
The FLD0 is clear. FLC0 = ln[1 + (23.3 + 14.13t)n/21].
The left side is also clear, by Goodwin method. e1 = FLC0 - e2, where e2 <= 0
But for the right side... I'm not sure. The Pam Stamp documentation says that uses Goodwin's and Keeler's law, but searching in google, the empirical equation that I find for Keeler doesn't match with PAM STAMP.
Anybody knows which formula is used by Pam Stamp?
I just attached a comparative with the parameters: n = 0.2, t = 1.5 mm
Thanks in advances
