Abstract
Blast loading tests have been developed in air by using ANSYS-AUTODYN program for simulation. The fourteen simulated models mainly conducted in four phases as first phase is discussing four models grouped in Group 1 consists of four concrete blast walls with double layer that subjected to four different masses of TNT (10, 50, 100, 500) kg. The main purpose for this group results to choose the proper TNT mass to use in the next phases of the research to make the comparison between models, involving pressure and damage, more obvious. The most appropriate mass is 100kg TNT to differentiate the results easier between the models. The second phase is discussing four models grouped in Group 2 consists of four different materials (Aluminum, Steel, Polycarbonate, Platinum) used in forming hexagon core between the concrete double layers (Sandwich Panel). Comparing their output results with the concrete double layer wall without core. However, Aluminum core showed the best output results. The third phase is discussing three models grouped in Group 3 consists of three blast walls models with three different angels of curvature. The best curvature observed is depending on the barrier’s aspect ratio and it can resist better by its concave side not convex side.
