In this paper we analyze the delamination problem of a two-layer plate by means of a unilateral contact approach. The mathematical formulation of the problem is discussed and a finite element approximation is presented. Two numerical examples concerning one — dimensional and two-dimensional problems are examined. Some comparisons with analytical results are also given, which show the effectiveness of the unilateral approach.

In questo lavoro si esamina, mediante un approccio di tipo contatto unilaterale, il problema di delaminazione di pannelli compositi a due strati. Si discute la formulazione matematica del problema, di cui si presenta una approssimazione mediante elementi finiti.

I risultati numerici ottenuti riguardano un problema di delaminazione monodimensionale ed un altro bidimensionale.

Il confronto di questi risultati con soluzioni analitiche disponibili mostra l’efficienza del modello proposto.
