Abstract

Edge debonding initiation and propagation in beams strengthened with fiber-reinforced composite plates is here studied. The structural system is composed by three physical components, namely the beam, the adhesive layer and the bonded plate, which are modeled by one or several first-order shear deformable layers according to a multi-layer formulation, wherein both strong and weak interface constitutive relations are introduced to model interfaces. Debonding onset is predicted with the aid of a mixed mode coupled stress and energetic criterion, and propagation in different locations across the adhesive thickness is studied by using a mixed mode fracture criterion. The proposed models are implemented according to the 1D finite element technique, allowing accurate evaluation of interlaminar stresses and fracture energies.
