Dear all,
I am trying to model interaction between longitudinal reinforcement and surrounding concrete using 2D-FE available in ABAQUS package as shown in attachment.
The model was defined as 2D Plane Stress. The concrete beam was modelled using CPS4R element whereas the reinforcing bar was modelled using truss element T2D2. It is important to mention that the truss element was created by using 2D Deformable Wire.
In some published articles (See below), I found that using Cohesive Element (COH2D) is possible when using wire as a reinforcing bar. However, none of the authors explained how the interaction was created between reinforcing bars as Wire (T2D2) and Concrete beam by using cohesive element.
It was not clear whether they have divided the concrete block into two parts to define cohesive element and reinforcing bar in between or kept it as one block and embedded the reinforcement into concrete.
Have any of you tried to use cohesive element to define interaction between concrete and reinforcing bar in 2D environment, especially Wire as a reinforcing bar and CPS4R as a concrete?
Published papaers where COH2D was employed.

Hi,
Some of those was not for elastic case and not reinforced with steel, so you should check the stiffness parameters and limits.
Kind regards
Hello,
You could use an adhesive polymer has -OH group to increase the cohesion

Hi Almahdi Mohamed Araba ,
Have you found out how to model cohesive element (COH2D) to apply interaction between a reinforcing bar as Wire and Concrete in 2D-FE? Am looking for the same.
Best Regard,
Naveen.
