Feigenbaum-Dafalias model
The Feigenbaum-Dafalias directional distortional hardening model, type $\alpha$ with constant $c,$ is described by the following parameters:
- $k_0~[\text{Pa}]$
- $\kappa_1~[\text{Pa}]$
- $\kappa_2~[1/\text{Pa}]$
- $a_1~[\text{Pa}]$
- $a_2~[\text{Pa}]$
- $c~[1/\text{Pa}]$
Input quantities
Material quantities are defined in the file name.i2, where the parameters $k_0,\kappa_1,\kappa_2,a_1,a_2,c$ are entered on the 9th–14th position of the MP batch:
MP set number T 1 V $E$ 0 $\nu$ 5*0 $k_0$ $\kappa_1$ $\kappa_2$ $a_1$ $a_2$ $c$
The model is activated by the key $\mathtt{KMOD}=4$ in the file name.iP.
