Abaqus tutorials Abaqus tutorials
In this tutorial, the Simulation air blast explosion over the UHPC slab reinforced with BFRP composite in Abaqus has been investigated. The Ultra-High-Performance-Concrete is modeled as a three-dimensional solid part. The Basalt fiber reinforced plastic(BFRP) is modeled as a shell part with four layers. You can see a figure of the assembled parts below
The Concrete-Damaged Plasticity is used to model non linear behavior of the UHPC. In this model the tensile and compression data are define separately and also tensile and compression damage can be used. Laminated fiber reinforced composite materials are increasingly used in various industries such as aerospace, military, marine, car manufacturing etc, to their superior specific strength and stiffness, convenient fabrication of complicated products and structures, corrosion and environmental resistance as well as their competitive cost for fabrication. The elastic model lamina type and Hashin’s damage criterion is used to model BFRP behavior under the blast load. The dynamic explicit step is appropriate for this type of analysis. The ideal contact is selected between UHPC surface and BFRP composite parts. The COWEP blast explosion procedure is considered. In this way, the amount of the TNT and its locations should be define. The fixed boundary condition is assigned to the the sides of the slab . The mesh should be fine to achieve the correct results during the blast load
After the simulation, all results such as stress, strain, tensile and compressive damage, fiber damage criterion, force diagram, displacement diagram,… are available. You can see some figures for the results below
