In this tutorial, the simulation of a dynamic bending test of a rubberized concrete beam reinforced with green composite in Abaqus has been investigated.
The rubberized concrete beam is modeled as a three-dimensional solid part. The green composite reinforcement is defined as a three-dimensional shell part with four layup layers. Steel bars and strips are modeled as three-dimensional wire parts. Two shell rigid bodies are used to simulate hydraulic jacks.

This simulation introduces rubberized concrete composite as a novel structural material. The Concrete Damaged Plasticity (CDP) model is used to represent the behavior of the rubberized concrete beam under dynamic bending conditions. For the green composite material, elastic lamina properties combined with the Hashin damage criterion are employed. Steel components are modeled with elastic-plastic behavior.

The analysis uses a dynamic explicit step with mass scaling to accelerate the simulation and minimize inertial effects. A tie constraint is applied to connect the concrete beam and green composite. Steel bars are embedded within the rubberized concrete. Surface-to-surface contact with frictional properties is defined between the rigid jacks and the beam. The load is applied through the jacks, while fixed boundary conditions are assigned at both ends of the beam. A refined mesh is used for accurate results.

After completing the simulation, results such as stress, strain, damage in both concrete and composite, and force-displacement diagrams are available for analysis.
