Hi Aniket, I 'm using the same model that you mentionned (modified time hardening). I obtained the constants (creep parameters) using the Creep Fitting Curve in ADPL, in correlation with experimental data. Like you said, I think the error is probably due to these parameters, but I can't understand clearly what you noted :

"From the end of load step, first substep get a peak stress value of the creep material and solve for creep strain in Excel. There is an imposed displacement on the model, so we can assume that the stresses will probably increase, but add values for additional increments of time, keeping stress the same. nSee if the creep strains are reasonable"

Can you pls explain more in detail of this solution ? 

Thank in advance for your help
