Simulation four points bending of Ultra High Performance Concrete beam with steel beam core in Abaqus

In this tutorial, the Simulation four points bending of Ultra High Performance Concrete beam with steel beam core in Abaqus has been done. UHPC possesses a compressive strength greater than 21.7 ksi (150 Mpa) and a flexural strength greater than 0.72 ksi (10 Mpa) at 28 days. The concept of UHPC was first developed by Richard and Cheyrezy and was produced in the early 1990s at Bouygues Laboratory in France. The mechanical properties of both plain and fiber-reinforced UHPC mixtures proportioned using commercially available materials. The UHPC beam is modeled as a three-dimensional solid part. The steel beam as a core is modeled as a three-dimensional solid part. The rigid bodies as boundary zone and hydraulic jacks are modeled as rigid shell parts. You can see figures of the assembled parts below

The Concrete Damaged Plasticity is used to model the UHPC beam. The model is a continuum, plasticity-based, damage model for concrete. It assumes that the main two failure mechanisms are tensile cracking and compressive crushing of the concrete material. The material data is extracted from the reference paper. The steel material with elastic-plastic data and ductile damage criterion to predict damage during the bending process for the steel beam core is used. The general static step with some changes in the convergence model is implied. The surface to surface contact with friction as a contact property is considered between the rigid bodies and concrete beam. The contact between the steel beam core and the concrete beam is considered as a perfect or ideal contact. The fixed boundary condition is assigned to the two bottom rigid bodies and displacement is applied with the amplitude to two top rigid bodies. The mesh should be fine to obtain good results

After the simulation, all results such as stress, strain, damage, force-displacement diagram, and…are achievable. You can see some figures for the results below
