Simulation four points bending of the reinforced rubberised concrete beam in Abaqus

In this tutorial, the Simulation four points bending of the reinforced Rubberised Concrete(RuC) beam in Abaqus has been investigated. The RuC beam in modeled as three-dimensional solid part. The steel bars and strips are modeled as three-dimensional solid parts. Two rigid bodies are modeled to apply load instead of hydraulic jack. You can see a figure of the assembled parts below

Vulcanized rubber material extracted from end-of-life tyres is highly durable, has good strength and deformability, and can maintain its volume under stress, thus making it an ideal candidate to replace mineral aggregate for highly deformable concrete. The feasibility of utilizing recycled rubber as aggregate in concrete has been assessed by many studies in the past. There many type of the RuC material with different volume fraction of rubber in the concrete material. In this simulation a 30% rubber in the total volume base on the reference paper is used. The CDP plasticity model is used to consider both compressive and tensile behavior of the RuC beam. The elastic-plastic material model is used for the steel bars and strips. The general static step with some changes in the convergence model to avoid early not convergence is considered. The perfect contact is assumed between the rigid bodies and RuC beam. The bars and strips are embedded inside the concrete host. The fixed boundary conditions is assigned to to ends of the beam. The displacement load is applied to the two rigid bodies like the hydraulic jack. The mesh should be fine and proper to obtain correct results

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