VALUTAZIONE DELLA RESISTENZA DI ADESIONE E DELLALUNGHEZZA EFFICACE DI INCOLLAGGIO NEI GIUNTI ADESIVITRAMITE LE LEGGI DELL’EFFETTO SCALA

In recent years, growing attention has been paid by researchers in structural mechanicsto bonded joints in order to provide theoretical and numerical tools for better understandingthe interfacial bonding/debonding phenomena. The research efforts in this area regard the formulationof reliable bond-slip models based on experimental data coming from laboratory testsperformed on small specimens [1, 2].As reported in [3], the mechanical quantities characterizing any interface constitutive law canbe derived from the results of the experimental pull tests by a simple procedure making use of aschematization of the structural problem. The application to some single lap joint tests, carriedout at the DISAG Laboratory of Palermo University, shows the effectiveness of the procedure.
