The following are JMAK parameters for the hardening calculation
| JMAK Parameter#i = PSetID;t0;Q;n;Y0;R |
Define the JMAK parameter in the order provided. The first value in the mapping command refers to a part set in the source mesh that is assigned with the respective parameters for calculating the hardening degree. All parameters must be seperated by a semi-colon. If the same parameter set is assigned to all parts, use JMAK Parameter#i=ALL;t0;Q;n;Y0;R. This option also allows assigning some parameters to specific part sets, and the remaining parts use the parameters in the JMAK Parameter#i=ALL;... option. |
| Y POS = &HISV#i |
Defines the history variable position i where the hardening degree is assigned to. |
The JMAK equation is given by:
(5–12) |
with:
(5–13) |
where
T = the Temperature (in degrees C)
R = the gas constant
Y = the resulting hardening degree
Y0 = the initial hardening degree
t0, Q, and n can be determined by experiments
