In this tutorial, Simulation crack growth in the RC beam under five points bending in Abaqus has been investigated. The concrete beam is modeled as a three-dimensional solid part. The bars and strips are modeled as three-dimensional wire parts. The rigid bodies as supporters and hydraulic jacks are modeled as three-dimensional rigid shell parts. You can see figures of the assembled parts below
Traction-separation law is used to model concrete behavior and crack growth. The response of cohesive behavior in the enriched elements in the model is specified. The maximum principal stress failure criterion is selected for damage initiation, and an energy-based damage evolution law based on a power-law fracture criterion is selected for damage propagation. The steel material with elastic-plastic data is used for the bars and strips. The general static step with some changes in the convergence algorithm is applied. The steel members are embedded inside the concrete host and the surface to surface contact with friction as a contact property is used among all rigid bodies and concrete beam. The XFEM procedure to study crack growth is implied to monitor crack propagation in the RC beam. The fixed boundary condition is selected for the three bottom rigid bodies and displacement for the two top rigid bodies. The mesh should be fine to have a better prediction of the crack path.
after the simulation, all results such as crack propagation, stress, displacement, and XFEM outputs are achievable. You can see some figures for the results below
