[Fluid-Structure Interaction Case] Destruction Behavior of Reinforced Concrete Slabs Due to Underwater Explosion

The water confinement effect is more powerful compared to air explosions! This is a case that shows the destruction situation of the RC version is significantly different.

This is a case study that examines the destruction behavior characteristics of reinforced concrete slabs (RC slabs) due to underwater explosions through numerical simulations using coupled structural-fluid analysis. The explosive used is the H51 model (Pentolite 51g), and the pressure calculations for the model utilize the JWL (Jones-Wilkens-Lee) equation of state. For water, the compressibility is taken into account using the GRUNEISEN equation of state. As a result, in the case of underwater explosions, the RC slab experiences shear failure due to the immense pressure from the water's confinement, while in the case of aerial explosions, craters, spall failures, and cracking occur on both the top and bottom surfaces of the RC slab.
