I calculate the deformations at time 0 and at time infinite. The deformations at the time infinite seem plausible to me. The deformations at time 0 seem significantly smaller and therefore implausible. What is the reason?

Answer

Please check if the structure tears due to pure load. It is possible that the increase in deformations is mainly caused by creep and shrinkage, which are not active at time 0. In the nonlinear calculation, shrinkage is considered as a strain load, which can cause additional stresses.
