Simulation four point bending of the UHPFRC beam in Abaqus

In this tutorial, the Simulation four point bending of the UHPFRC beam in Abaqus has been done. The UHPFRC beam is modeled as a three-dimensional solid part. Steel bars and strips are modeled as three-dimensional wire part. Two rigid bodies are used as hydraulic jack to apply the displacement on the top surface of the beam. You can see a figure of the assembled parts below

Ultra-high performance fibre reinforced concrete (UHPFRC) is an advanced cement composite material, which is characterised by high strength, ductility, durability and fracture toughness. UHPFRC is generally characterized as the reactive powder concrete with compressive strength exceeding 150 MPa containing sufficient fiber content to achieve strain hardening under tension.Since its conception, various proprietary UHPC mixes have been developed such as: SIFCON, Ductal, CARDIFRC and CEMTEC, however due to the cost and specialist curing requirements of these materials use in practice has been limited to several land-mark structures. In an attempt to further expand the usage of UHPC by simplifying manufacture techniques and reduce costs. The CDP material model is used to define compression and tensile behavior of the UHPFRC beam. The elastic-plastic material model is used to define steel bars and strips. The general static step with some changes in the convergence model to avoid early not convergence is selected. The contact between rigid bodies and beam can be the ideal or surface to surface contact. The strips and bars are embedded inside the concrete host. The fixed boundary condition is assigned to the two ends of the beam and displacement as a load is assigned 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, force-displacement diagram, and … are available. you can some figures for the results below
