Changing material properties between steps
Changing material properties between steps
(OP)
Dear All,
I use Abaqus 6.10. to perform two different analyses with 5 steps. In the first analysis material properties (elastic+plastic+creep)remain the same in all steps. However, in the second one the effect of material plasticity should be ignored after 3rd step. How can I do this change of material properties in the second analysis? I suppose that it is necessary to apply field variable. However, I did not know to do this. Any help will be highly appreciated. Here are material properties:
*Material, name=Material-1
*Creep
5e-16,5.,0.
*Elastic
210000., 0.3
*Plastic
400., 0.
425., 0.01
450., 0.05
475., 0.09
500., 0.13
525., 0.18
550., 0.23
600., 0.4
650., 0.49
700., 0.57
Regards

RE: Changing material properties between steps
Working with field variables is not difficult. Make you material dependent of one (can be done in /CAE) and then add *Field with reference to an amplitude to define when you want to have what value of the field variable.
Request FV as Field Output to see the value of the field variable in postprocessing.
See Abaqus Analysis Users Guide 34.6.1 Predefined fields

An option may be, that you create a new analysis and map the existing results. See keyword *Map Solution.
