In this tutorial, the Simulation Pull-Out test of a ribbed steel bar from the UHPC part in Abaqus has been investigated. The steel bar is imported to Abaqus from the CAD software because of the complex geometry as a solid part. The Ultra-High-Performance-Concrete is modeled as a three-dimensional solid part. You can see a figure of the assembled parts below
The performance of bond behavior between steel bars and concrete depends mainly on the following three factors: chemical adhesion, friction, and mechanical interlock. Over the past few decades, a series of studies have discovered the technique for improving the bond behavior of bars inside concrete. The pull-out load (bond strength) increases with the embedded length and the diameter of the rebar. The failure mode of post-installed rebar concrete is governed by the embedded length and the area of contact with the adhesives or binder
The concrete damaged plasticity (CDP) model is one of the most popular material models for plain and reinforced concrete implemented in Abaqus software. It is theoretically described by Lubliner et al. and Lee and Fenves. The use of this model requires values of some material constants. In this example, the CDP model is selected to demonstrate the tension and compression behavior of the UHPC in the pull-out test. The tension and compression
damage with some changes in the keyboard file are considered also. The elastic-plastic material data is considered for the ribbed steel bar
The dynamic explicit step with mass scale technique to reduce the time of the simulation is used. The proper contact property is assigned to all surfaces of the bar and concrete. The proper mesh and boundary conditions are assigned to the parts
After the simulation, all results such as stress, strain, tension and compression damage, failure, force-displacement diagram, and others are available. You can see some figures of the results below
