Simulation four-point bending of a concrete beam reinforced with steel bar and BFRP in Abaqus

In this tutorial, the Simulation four-point bending of a concrete beam reinforced with steel bar and BFRP in Abaqus  has been done. The concrete beam is modeled as a three-dimensional solid part. The Basalt Fiber reinforced Plastic(BFRP) is modeled as a shell part with four layers. The strips and bars are modeled as three-dimensional wire part. Some rigid bodies also used as hydraulic jack to apply load. You can see figures of the assembled parts below

The Concrete Damaged Plasticity is used to model concrete beam behavior. 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 steel material with elastic and plastic model is selected for the strips and bars. To model the BFRP composite, elastic data lamina type and Hashin’s Damage criterion is used. Damage initiation refers to the onset of degradation at a material point. In Abaqus the damage initiation criteria for fiber-reinforced composites are based on Hashin’s theory. These criteria consider four different damage initiation mechanisms: fiber tension, fiber compression, matrix tension, and matrix compression. The general contact capability with some changes in the convergence model to avoid early not convergence is selected. The surface to surface contact algorithm is selected to define contact between rigid bodies and concrete beam. The embedded region constraint is used for the steel bars and strips. The perfect contact is assigned to the interface zones between concrete and BFRP. The fixed boundary condition is assigned to the bottom rigid bodies and displacement to the top rigid bodies. The mesh should be fine to obtain correct results

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