Close In Detonation Against Reinforced Concrete Structural Elements
The first image depicts a numerical simulation of a close-in detonation against a reinforced concrete structural element, accurately modeling shockwave propagation and structural deformations. The second image shows the actual physical detonation, where the observed damage closely mirrors the aforementioned simulation’s predictions. This strong resemblance validates the accuracy of the numerical model in predicting RC structure behavior under extreme blast conditions.
Fiber-Reinforced Polymer (FRP) Masonry Wall - Subjected to Blast Loads
The first image presents a numerical simulation of a close-in detonation against a fiber-reinforced polymer (FRP) masonry wall, capturing the intricate interactions between the blast waves and the composite material. The simulation accurately predicts stress distribution, wall deflection, and potential failure mechanisms within the FRP-reinforced structure.
The second image shows the aftermath of an actual close-in detonation against an FRP masonry wall. The damage observed, including cracking patterns and deformation, closely aligns with the simulation’s projections. This close correlation between the simulated and real-world outcomes underscores the effectiveness of advanced modeling techniques in predicting the blast resistance of FRP-reinforced masonry walls.
Please note that two sets of perspectives are shown in this example.
