In this tutorial, the Dynamic bending simulation of a UHPC beam reinforced with GFRP bars in Abaqus has been investigated. The Uktra-High-Performance concrete beam is modeled as a three-dimensional solid part. The cohesive layer as an interface between UHPC and GFRP bar is modeled as a three-dimensional solid part. The GFRP is modeled as a three-dimensional solid part and the two rigid parts have been used to apply the load. You can see a figure of the assembled parts below
To model UHPC material, Concrete Damaged Plasticity model is used. This hardening model is used both compression and tension data to simulation the UHPC behavior under dynamic bending load. To model cohesive layer, the elastic data type traction and also traction-separation law to consider failure is used. To model GFRP behavior the elastic data as an engineering constant is selected. The dynamic explicit step us appropriate for this type of analysis because of the large deformation and separation that happens during the bending between the UHPC and the GFRP bars. The general contact algorithm with friction as a contact property is selected to consider all contacts. The perfect or ideal contact is applied to the surface of the concrete and cohesive layer, GFRP and cohesive layer. The fixed boundary condition is assigned to the two bottom surfaces of the beam and displacement with amplitude to the two top rigid bodies. The mesh be fine to achieve the good results
After the simulation all results such as stress, strain, plastic strain, displacement, force-displacement diagram, and … are available. You can see some figures for the results below
