A mechanical model to study the behavior of a curve adhesive joint is presented. In order to identify the governing parameters of the joint response, the coupling between shear/flexure and extensional equilibrium problems, the curvature radius, the energy mobilization corresponding to the most common cohesive interface laws have been introduced. Such model represents a generalization of a previous one introduced by the same authors relative to joint with straight axis. With reference to a concrete beam reinforcement with FRP, a wide numerical investigation has been developed in order to highlight the influence of curvature radius in terms of absorbed fracture energy as function of the load level.

Abstract
A mechanical model to study the behavior of a curve adhesive joint is presented. In order to identify the governing parameters of the joint response, the coupling between shear/flexure and extensional equilibrium problems, the curvature radius, the energy mobilization corresponding to the most common cohesive interface laws have been introduced. Such model represents a generalization of a previous one introduced by the same authors relative to joint with straight axis. With reference to a concrete beam reinforcement with FRP, a wide numerical investigation has been developed in order to highlight the influence of curvature radius in terms of absorbed fracture energy as function of the load level.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
