Hiya,

I have different stress strain curves at different hours (1hr, 10hr, 100hr).  for a constant stress, the strain increases with increase in number of hours(creep)

They look like stress-strain curves at different strain rates.

now I want to define a material card with these curves with above mentioned number of hours.

I kindly request you to suggest me a CARD in ABAQUS which takes care of this behavior.

Thanks a ton for your help, in advance !
