The value of IDENT allos automatic computation of $N_j$ using a user-defined criterion.
The structure to define the parameters for a specific IDENT is the following:
First line | NPAR = number of parameters for this IDENT |
Second line | PARAM(1:NPAR) = parameters for this IDENT |
Chaboche law.
The value of $N_j$ is defined to keep the increment of total damage below $(\Delta D)_{max}$.
NPAR | 4 |
PARAM(1) | $N_{AF}$ |
PARAM(2) | $N_{AF,Y}$ |
PARAM(3) | $(\Delta D)_{max}$ |
PARAM(4) | $(N_{jump})_{max}$ |
Chaboche law.
The value of $N_j$ is defined to keep the increment of total damage below $(\Delta p)_{max}$.
NPAR | 2 |
PARAM(1) | $(\Delta p)_{max}$ |
PARAM(2) | $(N_{jump})_{max}$ |
Chaboche law.
The value of $N_j$ is defined to keep the increment of equivalent plastic strain below $(\Delta p)_{max}$ and the increment of total damage below $(\Delta D)_{max}$.
NPAR | 5 |
PARAM(1) | $N_{AF}$ |
PARAM(2) | $N_{AF,Y}$ |
PARAM(3) | $(\Delta D)_{max}$ |
PARAM(4) | $(\Delta p)_{max}$ |
PARAM(5) | $(N_{jump})_{max}$ |
