Abstract (EN): Implicit solutions in viscoplastic analysis of structures are very often avoided due to the fact that they lead to non-symmetric systems of equations. On the other hand, structures such as soils have a marked non-associate behaviour that has to be taken into consideration. Here the implicit solutions are formulated in a way that, even for non-associate models, the system of equations is kept as symmetric. Apart from an 'exact' formulation of the algorithm other possibilities are considered and tested in the numerical examples given.
