| ~creepdam (void) | |
This class defines artificial material model which combines a creep model with damage model
Order of internal variables in the other array : ----------------------------------------------- The first components of eqother array belong to creep model, followed by the damage eqother components and optionally followed by the thermisomatttime components
Exact order of the components depends on the used material models.

| void nlstressesincr | ( | long | ipp, | |
| long | im, | |||
| long | ido | |||
| ) |
This function computes correct stresses in the integration point and stores them into ip stress array. It was used for Hinkley computations and supposes creep strains to be read from backup file.
| ipp | - integration point pointer 7.10.2001 |
void creepdam::nlstresses (long ipp) { long i; long ncomp = Mm->ip[ipp].ncompstr; vector epsback(ncomp);
backup of the total strains for (i=0;i<ncomp;i++){ epsback[i] = Mm->ip[ipp].strain[i]; }
compute creep - actually it is supposed the creep strains are read from backup file to the eqother array. initial values of elastic strain for damage = total strain - creep strain for (i=0;i<ncomp;i++){ Mm->ip[ipp].strain[i] -= Mm->ip[ipp].eqother[i]; }
compute damage, it has index 1, eqother values for damage starts at ncomp index Mm->computenlstresses(ipp, 1, 2*ncomp);
recovery of the total strains for (i=0;i<ncomp;i++){ Mm->ip[ipp].strain[i] = epsback[i]; }
} This function computes stresses increments fro creep model in the integration point and stores them into ip stress array.
| ipp | - integration point pointer | |
| im | - index of the material in the ipp tm and idm arrays. The standard value is zero. | |
