Summary
In this paper the complex mechanism of debonding-peeling failure of fibre-reinforced polymer (FRP) reinforcement is studied, with a three-dimensional approach, within the context of damage mechanics to appropriately model transverse effects and develop a more realistic and comprehensive study of the delamination process [1,2,3,4,5].

The system is viewed as composed by three different physical basic layers: the concrete support, the adhesive layer and the composite strip. The adhesion has been reconstructed by means of a contact model and an elastic-damage constitutive law which relates interlaminar stresses acting in the sliding direction.

The ABAQUS finite element code has been supplemented with a numerical procedure accounting for Mazars's damage law inside the contact algorithm. The coupled behaviour between concrete, FRP and adhesive, resulting in specific bonding-debonding features under different load levels, has consequently been attained. It is shown that such an approach is able to model the delamination evolution during the loading processes.
