5.23.6. JMAK Parameters

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
