Abstract
In this paper the symmetry concept is introduced for descriptions of the mechanical behaviour of materials. For any material there exist infinite descriptions for its mechanical behaviour whose symmetry groups need not be the same. It has been proved that any anisotropic description can be transformed into an isotropic or another anisotropic description whose symmetry group is a little larger than the original one. The concepts of reference configuration, reference state and reference element are introduced for a deseription. The method to calculate deformation induced anisotropy is also provided.
Sommario
Nel lavoro viene introdotto il concetto di simmetria per la descrizione del comportamento meccanico dei materiali. Per ogni materiale esistono infinite descrizioni per il suo comportamento mecanico in cui non e' necessario che i gruppi di simmetria siano gli stessi. E' stato provato che ogni descrizione anisotropa puo' essere trasformata in una isotropa od in un'altra anisotropa il cui gruppo di simmetria sia un po' piu' ampio diquello originale. Vengono introdotti i concetti di configurazione di riferimento, stato di riferimento ed elemento di riferimento di una deserizione. Si riporta anche il methodo per calcolare l'anisotropia indotta dalla deformazione.
