This tutorial investigates a Simulation air blast explosion test over a reinforced UHPC- Damage analysis. The Ultra-High-Performance Concrete is modeled as the three-dimensional solid part. The embedded bars and strips parts are modeled as a three-dimensional wire part. You can see a figure of the assembled parts below
The UHPC slab is used in recent modern structures because of its high compressive strength. The Concrete Damaged Plasticity Model (CDPM) was used for defining the two main mechanisms of concrete failure: tensile cracking and compressive crushing. The CDPM was fed stress-strain values in the compression and tension, relying on the test compressive strength of concrete. The CDP model is not appropriate for the concrete under blast load. To have proper behavior under high string load, we should use a new material model for the UHPC which is available from the input files as writing codes, or VUMAT subroutine. For the steel parts, elastic-plastic behavior is selected
The dynamic explicit step is selected for this analysis. The steel reinforcements are embedded inside the concrete column. The fixed boundary condition is assigned to two sides of the column. To model blast load, the CONWEP procedure is selected. The mesh should be fine to obtain correct results
After the simulation, all results such as stress, strain, failure, damage, and… are available. you can see some figures for the results below
You can provide CAE, INP, and English video files of this simulation here. The cost of these files is Thirty Euros. you can click on the bellow bottom to begin the process
