Hello guys,
I did an inverse analysis procedure to match my stress-strain model of my concrete with the result of the 3-point bending test. After the model is adjusted, I am trying to simulate a large beam, with reinforcement and stirrups. Although the graph is similar (see figure) the maximum force gives approximately 50% greater. I've already changed contact conditions, refined mesh, changed analysis time and the peak continues to be much higher. Does anyone have any suggestions of something I can change in Abaqus? I'm using explicit parsing and the CDP model
