Comments
 Small strain formulation is activated from time t=0, if I_{smstr} =1. It may be used for a faster preliminary analysis because $\text{\Delta}t$ is constant, but the accuracy of results is not ensured.
 The strains and stresses which are given in material laws are engineering strains and stresses. Time history output returns engineering strains and stresses.
