MSC Marc/ Chaboche hardening rule parameters

[Rob767]

Hello I am trying to figure out what these parameters are, and how to use them in an efficient way. I am looking for information describing the parameters and what they do, ( how they affect the solution, which ones to use,not use, what values to use etc...)


R0 for isotropic hardening.
R? for isotropic hardening (Q0 in case of using
plasticstrain-range memorization, see 5c data block)
b coefficient for isotropic hardening.
C coefficient for kinematic hardening.
? coefficient for kinematic hardening.
K value for viscosity model.
n coefficient for viscosity model.


Qm coefficient for isotropic hardening.
? coefficient for isotropic hardening.
? coefficient to introduce progressive memory.

If anyone could give some hints i would really appreciate it. Thanks for your time.
