Reply To: Issue of creep integration algorithm does not converge

Hello Peteroznewman

Thank you very much for your comment.

I tried your suggestion, and set the negaptive constant C2 to 0 for rectangular specimen under 110°C condition(no convergence issue for this simple case too). But simulation result shown significant difference, even the absolute value of C2 is much smaller than C1, C4 and C5
