hyperelastic and viscoplastic behavior
hyperelastic and viscoplastic behavior
(OP)
Hello
Please i have to model an elastomeric ring all what i know is that is made from polyrethane so i supposed that it's behavior is hyperelastic and viscoplastic orviscoelastic with hysteresis. Can anyone tell me if it is necessary to write a umat to caracterize my material. Or it is sufficient to fill in abaqus the hyperelastic and viscoelastic and mullins effect options. Can any one tell me how to do
thanks a lot

Please be careful of subroutines or advanced material modeling unless you have a LOT of expert help.
