Simulation static bending of the UHPC beam with CFRP pipe core in Abaqus

In this tutorial, the Simulation static bending of the UHPC beam with CFRP pipe core in Abaqus has been investigated. The concrete beam is modeled as three-dimensional solid part. The CFRP pipe core is modeled as a three-dimensional shell part. The rigid body part is used as a force body.You can see a figure of the assembled part below

It is widely accepted that composite structures can contribute to a more effective and efficient structural system. In recent years, fiber reinforced polymer (FRP) composite structures have found wide application in civil engineering. The characteristics of FRP include high strength to weight ratio, high durability (especially corrosion resistance) and the good installation property. Although concrete is the most universally used material in building there are still some limitations to its use, such as low tensile strength and brittleness. Ultra-High Performance Concrete (UHPC), a cutting-edge concrete, may be able to overcome these concerns. To model Ultra-High-Performance concrete material, Concrete Damage Plasticity model is used to consider both tensile and compression behavior. To model CFRP composite material, the lamina elasticity and Hashin’s damage criterion is used to predict the damage during the bending. The general static step with some changes in the convergence model to avoid early not convergence are used. The perfect contact instead of surface to surface contact is assumed between CFRP pipe and concrete inner surface. The general contact algorithm with friction property is consider for all other contact in the contact domain. The fixed boundary condition is assigned to the two surfaces of the UHPC and displacement boundary to the rigid body as a load control model. The mesh should be fine to achieve the good results

After the simulation, all results such ass stress, strain, damage, failure, and force-displacement diagram is available. You can see some figures for the results below
