Simulation dynamic compression test of a concrete column reinforced with CFRP bars in Abaqus

In this tutorial, the Simulation dynamic compression test of a concrete column reinforced with CFRP bars in Abaqus has been investigated. The concrete column is modeled as a three-dimensional solid part. The CFRP bar is modeled as a three-dimensional solid part and two rigid bodies as supporter and hydraulic jack are used. You can see a figure of the assemble parts below

To model concrete behavior and consider its damage, the Concrete Damaged Plasticity model is selected. 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. To model CFRP bar behavior, elastic model as engineering constant type is considered. The dynamic explicit step to obtain failure zone and maximum force capacity is used. The explicit step is more applicable in this simulation than the static solver because of the huge not convergence which happens during the analysis. The general contact algorithm to consider all contact in the contact domain with friction as a contact property is used. The interaction between concrete and the CFRP bars are assumed as perfect or ideal contact. The fixed boundary condition is selected for the bottom rigid body and the displacement for the top. The mesh should be fine to obtain correct results

After the simulation, all results such as stress, plastic stain, tensile damage, compression damage, and force-displacement diagram is available. You can see some figures for the results below
