In this tutorial, the Simulation ultra-high-performance fiber-reinforced concrete beam under four points bending in Abaqus has been investigated. Extensive research and development efforts, over the past three decades, to improve properties of concrete have led to the emergence of ultra-high performance concrete(UHPC). UHPC possesses very high compressive strength, good tensile strength, enhanced toughness, and durability properties. However one of the main drawbacks of UHPC is its brittleness property. To overcome the brittleness of UHPC, fibers are often added to UHPC and this type of concrete is referred to as ultra-high performance fiber reinforced concrete(UHPFRC). The addition of fibers to UHPC can significantly improve its ductility, fracture toughness, and energy absorption capacity. The concrete beam is modeled as a three-dimensional solid part. The steel bari\ is modeled as a three-dimensional wire part. You can see a figure of the assembled parts at below
The steel material with elastic-plastic material is used for the bar and the Concrete Damaged Plasticity model is used for the concrete beam to define the compression and tensile behavior of the ultra-high-performance-fiber reinforced concrete. All the data are extracted from the reference paper. The general static step with some changing in the convergence model is used to calculate the failure from the force-displacement diagram. The surface to surface contact algorithm between rigid bodies and the concrete beam is implied. The bar is embedded inside the concrete beam host. The fixed boundary condition is assigned to the two bottom rigid bodies and displacement to the two top rigid bodies. The mesh should be fine to obtain good results
After the simulation, all results such as stress, strain, displacement…are achievable. The force-displacement diagram can show the failure zone accurately. You can see some figures for the results below
