In this tutorial, the Simulation four-point bending of the UHPC slab reinforced with steel bars and the GFRP sheet in Abaqus has been investigated. The UHP concrete slab is modeled as a three-dimensional solid part. The steel bars are modeled as three-dimensional wire parts. The GFRP sheet with eight layers is modeled as a three-dimensional shell part. The rigid bodies as supporters and force bodies are modeled as a three-dimensional rigid shell. You can see figures of the assembled parts below
The Ultra-High-Performace concrete material by using concrete damaged plasticity is used to model concrete slab behavior under bending load. The steel material with elastic-plastic behavior is selected to model bars. The GFRP sheet is modeled as an elastic material with engineering constant data and Hashin’s damage criterion is used to investigate the damage propagation during bending test. The genera static step with some changes in the convergence model to avoid early not convergence is considered. The surface to surface contact with contact property is used among the rigid bodies with UHPC slab and GFRP sheet. The steel bars are embedded inside the concrete host. The perfect contact is assumed between the UHPC slab and the GFRP sheet. The fixed boundary condition is assigned to the two bottom rigid bodies and displacement boundary is assigned to the two top rigid bodies with smooth amplitude to apply smooth load. The mesh should be fine for all parts
After the simulation, all results such as stress, strain, damage, force-displacement diagram,… are achievable. You can see some figures for the results below
