Initial stress from thermal to structural domain
Initial stress from thermal to structural domain
(OP)
Hi,
I have carried out a thermal analysis in which the structure is heated to 100 °C in the first load step and then cooled down to 25 °C in the second load step, using Solid45 elements .Heating the structure results in stresses higher than the plasticity limit. So I have used bilinear kinematic hardening model (BKIN) with a specified tangent modulus and yield stress. The consequent heating and cooling of the structure, with plasticity, results in the final structure to be deformed due to residual stresses.
Now I wish to do a electrostatic analysis on the final deformed structure using TRANS126 elemets. I have used ISWRITE and ISFILE, read, commands but after isfile, read the final deformed shape of the structure is not same as it was in the previous thermal analysis. It will be very helpful if some one have experience in this regard.
I have also tried to used INISTATE command but when I try to read the stress file using INISTATE I get following error;
The initial memory allocation (-m) has been exceeded.
