La classe di materiali elastoplastici considerata tiene conto di nonassociatività, incrudimento nonlineare e saturazione (nel senso che le variabili interne statiche sono soggette a vincoli convessi che definiscono una superficie di delimitazione). Con riferimento ad una discretizzazione spaziale per elementi finiti in variabili generalizzate, si dimostrano due teoremi di adattamento («shakedown») dinamico in base ad un approccio cinematico nel senso di Koiter, fondato su ipotesi costitutive alquanto generali e su opportune definizioni di cicli plastici ammissibili.
