Codice QDD 102 Titolo Elastic structures in adhesion interaction Data 2011-06-23 Autore/i Maddalena, F.; Percivale, D.; Tomarelli, F. Link Download full text Abstract We study a variational model describing the interaction of two 1-dimensional elastic bodies through an adhesive layer, with the aim of modeling a simplified CFRP structure: e.g. a concrete beam or a medical rehabilitation device glued to a reinforcing polymeric fiber. Different constitutive assumptions for the adhesive layer are investigated: quadratic law and two kinds of softening law. In all cases properties of the equilibrium states of the structural system are analytically deduced. In the case of adhesion with softening, the minimum length of the elastic fiber avoiding debonding failure is estimated in terms of glue carrying capacity and the constitutive parameter of the fiber.
