| Abstract |
An accurate and fast numerical simulation of coupled Computational Fluid Dynamics (CFD)-Computational Solid Dynamics (CSD) has many engineering, scientific and industrial applications. Within the industrial and engineering field, one can mention processes such as controlled demolitions, slope and tunnel excavation, protective structures to increase the safety of buildings or vehicles against terrorist attacks, military applications, open pit mines, fracking procedures in oil industry, fuel tank accidents, among many others. It is also of critical economic, territorial and social importance to study the security of vital infrastructures such as dams, bridges, tunnels, protective nuclear buildings, etc. against explosive attacks or accidents. Equally important is the estimation of explosive damage in urban environments as well as the extent and intensity of its effect.
The numerical methodology proposed is not limited to be applied to civil engineering, it must be noted that it could be potentially employed to assess deformations (with or without plasticity) due to gas-structure interaction in the aeronautical field, being able to model non-recoverable strains in the fuselage and how this effect can change the aerodynamics of the sample and/or its safety.
All these applications share a main aspect: it can be very difficult and costly to perform experimental assessment and multiple successive designs since it requires highly specialised equipment, instrumentation skills, etc; this is why numerical simulation can be a relevant and useful tool for industry and society.
Complementary to the numerical methodology, the BLAST_IT project aims to provide a detailed and relevant experimental data base in which several configurations of blasts in open pit mines and tunnels are monitored in terms of final profile, granulometry of the blasted material, cracked profile, etc, contributing to the validation not only of the numerical solutions developed within the project, but also to the literature, since all the information will be publicly available and stored according to the data management plan. |
