In this tutorial three point bending simulation of concrete slab reinforced with bars and FRP in Abaqus has been investigated.The widespread successful use of composite materials in the automotive, naval and sporting goods industries has resulted in a technology transfer to civil infrastructure applications. Fiber-reinforced polymers (FRP) are impacting the international concrete industry. FRP combines high-strength glass, carbon, and aramid fibers with polymer resins, and can be used as both internal and external reinforcement for concrete members. FRP provides an alternative to steel reinforcement in areas where seawater, deicing salts, and corrosives can destroy the structural integrity of a concrete member due to deterioration of the steel reinforcement. The design philosophy for FRP-reinforced concrete is based on principles of equilibrium, compatibility of strains, and the stress-strain characteristics of the materials involved. The brittle behavior of both FRP reinforcement and concrete must be considered. Crushing of the concrete or FRP rupture are the mechanisms that control the failure of the section. For concrete crushing, the Whitney rectangular stress block is used to approximate the concrete stress distribution at ultimate strength conditions. For FRP reinforcement, the linear-to-failure stress-strain relationship must be used
The concrete slab is modeled as three dimensional part with CDP material to observe damage propagation under bending load and epoxy-glass fiber as reinforcement is modeled as three dimensional shell part with elastic material couple with fail stress to check the fiber damage on the visualization.You can see a figure of assembled part at below
General static step is appropriate for this type of analysis. The contact between concrete and FRP is assumed as perfect contact. The concentrated force is applied to the rigid body in interaction with concrete slab and during the simulation the damage propagated on the slab. The zone which FRP is used experienced a little damage but the other area has a massive damage. You can see some figures of this simulation at below
