In this tutorial, the Simulation air blast explosion over campsite slab(UHPC-Steel) by using cohesive interaction in Abaqus has been done. The two steel covers are modeled as three-dimensional solid part. The Ultra-High-Performance concrete is modeled as a three-dimensional solid par. You can see a figure of the assembled parts below
Tailored cementitious materials, such as Ultra-High-Performance Concrete (UHPC), may significantly improve the blast resistance of structural panels. The material properties of UHPC, such as super-high tensile and compressive strengths, ductility, and good durability make UHPC attractive for various engineering structures, especially in bridge engineering. The popularly employed Concrete Damaged Plasticity (CDP) .The model is a continuum, plasticity-based, damage model for concrete. It assumes that the main two failure mechanisms are tensile cracking and compressive crushing of the concrete material. To model the UHPC slab, CDP model is selected and it can predict the tensile and compressive damage. To model steel behavior, the elastic and plastic material model is used. The dynamic explicit step is appropriate for this type of analysis. The cohesive interaction by using stiffness, fracture stress and energy is assigned to the steel- concrete surfaces as a contact property to investigate the separation during the blast. The CONWEP blast technique is used to model TNT and its location. The fixed boundary condition is assigned to two sides of the slab. The mesh should be fine to achieve the correct results
After the simulation, all results such as stress, strain, tensile and compressive damage, displacement, and… are available. You can see some figures for the results below
