This study explores innovative approaches for the simulation of fast transient fluid-structure interaction (FSI) in compressible flows that may lead to structure rupture and fragmentation. A partitioned approach is proposed that involves a Lattice Boltzmann Method (LBM) code for fluid dynamics and a non-linear explicit solid dynamics solver for the structure. The Lattice Boltzmann Method offers powerful characteristics for high-performance computations. In particular, LBM operations are inherently local and explicit, providing an advantage for parallelized computations. It is also easy to implement through automated multi-level cartesian mesh generation, making it well-suited to address FSI scenarios with rapid transient phenomena even for cases involving complex geometries. Fluid-structure interactions are considered using a diffuse forcing Immersed Boundary Method (IBM) as it offers favorable properties for computational efficiency in the case of highly deformable and moving FS interface. This allows a high level of fluid-structure coupling while preserving LBM computational performance. Within this framework, state of the art codes, ProLB and Europlexus, are integrated into a supervised coupling interface. Particular attention is given to the space and time discretization of each system in order to avoid computational overload. This achieved using a fully multi-scale coupling strategy, in time through a possible subcycling of the structure solver and in space through a multi-level mesh transfer. Validation is carried out across different cases within the framework of fast transient FSI, including the dynamic response of blast-loaded steel plate in shock tube.
