In this tutorial, the Simulation air blast load over a composite beam( UHPFRC- Steel beam with Shear stud) in Abaqus has been investigated. The Ultra-High-Performance-Fiber-Reinforced Concrete is modeled as a three-dimensional solid part. The stud is modeled as a three-dimensional solid part. The steel beam is modeled as a three-dimensional shell part. You can see a figure of the assembled parts below
The Ultra High-Performance Fiber Reinforced Concrete (UHPFRC) contributes to improving durability, service life and performance of the structure. During the last decades, the three major developments in cementitious composites were the significant increase in the compressive strength, ductility improvement, and workability enhancement. These achievements were the result of a granular packing optimization, the development of Fiber Reinforced Concrete (FRC) and the better understanding of the material rheology. In the latter case, the improvements in the models to describe concrete flow (Bingham fluid flow and stress growth method) lead to the development of Self-Compacting Concrete (SCC) and later to UHPC and UHPFRC. The Concrete Damaged Plasticity is used to model UHPFRC beam under blast load. The Johnson-Cook hardening and damage is selected to model steel stud and beam behavior under severe blast load. The dynamic explicit step is appropriate for this type of analysis. The general contact capability with contact property is selected. To define contacts between studs and UHPFRC, surface to surface contact or embedded constraint can be used. The CONWEP blast load procedure is selected to define the explosive load. The fixed boundary condition is assigned to the two sides of the beam. The mesh should be fine to obtain correct results
After the simulation, all results such as stress, strain, tensile damage, deformation, and… are available. You can see some figures for the results below
