In this tutorial, the Simulation pull-out process of the deformed steel bar from the concrete in Abaqus has been investigated. The goal of this simulation is the damage and failure zone analysis in the concrete slab. The concrete part is modeled as a three-dimensional solid part. The deformed steel bar is imported to software because of the complex geometry. You can see a figure of the assembled parts below
The deformed bar is modeled as elastic-plastic with steel material. The ductile damage criterion with evolution is used to define damage in the steel bar. That criterion can predict the damaged and failed zone during the simulation. The Abaqus has many material models for concrete which can be used in this simulation, but to obtain the real damage and failure in the concrete, the Johnson-Holmquist material model is selected. The Johnson-Holmquist model is good material model to predict dynamic failure in the brittle material which is available through a subroutine code or input file. The dynamic explicit step is appropriate for this type of analysis. The mass scale technique is used to reduce the time of simulation and make stability in the model. The perfect or ideal contact is selected between the bar and the concrete. The fixed boundary condition is assigned to the sides of the concrete and displacement with a smooth amplitude is assigned to the deformed bar. The mesh should be fine to achieve good results
After the simulation, all results such as stress, strain, damage and failure for the concrete, ductile damage for the bar, …are obtainable. You can see some figures for the results below
