Sommario
Si studia analiticamente l'evoluzione della superficie di plasticizzazione dei metalli in fase di incrudimento nel piano σ - τ. Il problema, che riveste notevole interesse teorico ed applicativo, viene risolto in forma completa nell'ambito della teoria degli slip e prendendo opportunamente in conto l'effetto Bauschinger.
Summary
The evolution of the yield locus of metals in the strain-hardening range is analytically studied in the σ - τ plane. The problem, of theoretical and technical interest, is completely solved by applying the theory of slip and by taking into account the Bauschinger effect.
